How to Sell Ancient Coins in Southern Oregon

Ancient coins are the category we evaluate most differently from everything else we buy. A pre-1965 US dime sells on silver weight; a Rolex sells on brand and model; an ancient Roman denarius sells on who issued it, where it was struck, what condition the surfaces are in, and whether the patina is genuine. The math for ancients runs in a completely different direction from the bullion math that drives most of the other guides on this site.

The honest baseline: most ancient coins we see are worth real money to collectors but not life-changing money to sellers. Common late-Roman bronzes, worn Byzantine follis, and ordinary Greek city-state coinage sell into established collector markets at modest per-piece prices. A smaller subset — high-grade Greek silver tetradrachms, Lydian electrum, important Roman gold, finest-known Byzantine solidi — carries serious value. We won't pretend the category is a lottery; most pieces are modest. But we evaluate every piece on its own merits and explain the reasoning.

Here's what we're going to cover, in order:

1. What an ancient coin actually is — and the line between ancient, medieval, and early modern.
2. Greek coinage — from electrum through the Hellenistic period.
3. Roman coinage — Republic, Empire, and provincial.
4. Byzantine coinage — the long survival of the Roman tradition.
5. Other ancient categories — Carthaginian, Parthian, Sassanid, Indian, and Chinese.
6. Authentication and provenance — the two issues that matter most.
7. NEVER clean an ancient coin — the universal rule, only sharper here.
8. Why we can't quote ancient coins over the phone — and the narrow exceptions.
9. Why local matters for ancient coins — in-person authentication is the only honest evaluation.
10. What to bring — and what not to attempt at home.

Then a quick recap so you walk into your appointment knowing what to expect.

What an ancient coin actually is

For our purposes, an “ancient coin” is anything struck before roughly 500 CE in the West or before the Tang Dynasty (618 CE) in the East. The Byzantine Empire is a special case — it extends the Roman tradition into the 15th century, and Byzantine coinage is conventionally treated as part of the ancient/medieval coin world even for late issues. The lines between ancient, medieval, and early modern are gradient; we apply expertise rather than calendar dates at the evaluation table.

Three categories that look ancient but aren't, and that matter for honest evaluation:

• Modern reproductions — sold as souvenirs or teaching pieces. Some are clearly marked “COPY,” some aren't. Many are cast rather than struck, with sharp seams and incorrect weight. We identify these quickly and tell you what you have.
• Counterfeit ancient coins — deliberate deceptions. The market has long known about specific counterfeit workshops (notably the “Slavey” forgeries from Bulgaria in the 1990s and 2000s) and how to identify them. We check for those when relevant.
• Medieval and early-modern coinage — pre-1500 European, Islamic dinars, Chinese cash. These have their own markets and we buy them too, but they're not strictly “ancient.”

Greek coinage

Greek coinage spans roughly the 7th century BCE through the end of the Hellenistic period (about 30 BCE, with the Roman annexation of Egypt). It includes the earliest coins ever produced and some of the most artistically important objects in human history. The broad periods we look for:

• Lydian electrum (c. 650–550 BCE) — the very first coins, struck in natural electrum (silver-gold alloy) in the kingdom of Lydia, modern western Turkey. Lumpy, oblong pieces with simple punch-mark designs on one side. Significant collector demand far beyond metal content.
• Greek archaic period (c. 550–480 BCE) — early city-state coinage from Athens, Aegina, Corinth, and others. Simple obverse types, incuse-square reverses.
• Greek classical period (c. 480–323 BCE) — the famous Athenian owl tetradrachms, Corinthian Pegasus staters, Aeginetan turtle staters, Syracuse decadrachms (some of the most desired ancient coins).
• Hellenistic period (323–30 BCE) — Alexander the Great tetradrachms (which continued to be struck long after his death), Seleucid kingdom issues, Ptolemaic Egypt bronzes and silver, Antigonid Macedonia, and smaller successor kingdoms.

Materials we see most: silver tetradrachms (the major denomination), smaller silver drachms and obols, bronze coinage from city-states, and the occasional gold piece. Greek gold is rare enough that any piece warrants careful evaluation.

Roman coinage

Roman coinage is the largest single ancient-coin category by volume and the one we see most. Three eras to know:

• Roman Republic (c. 280–27 BCE) — denarii are the main denomination, struck in silver. Republic denarii feature moneyer names rather than emperors and reference family histories on the reverse. Aes grave (cast bronze coinage) is a separate Republic-era category.
• Roman Empire (27 BCE–476 CE) — the bulk of what we see. Major denominations:
  • Aureus — gold, struck for about three centuries, the highest denomination.
  • Denarius — silver, the workhorse coin for centuries until debasement caught up with it in the 3rd century.
  • Antoninianus — double denarius introduced under Caracalla, increasingly debased until it became effectively bronze by the late 3rd century.
  • Sestertius, dupondius, as — large bronze denominations from the early Empire, often with the best portrait work in Roman coinage.
  • Follis — the late-Empire bronze introduced by Diocletian.
• Roman provincial coinage — bronzes struck by Greek-speaking cities of the eastern Empire (Alexandria, Antioch, Smyrna, and hundreds of others) with local types alongside the emperor's portrait.

Late-Roman bronzes (the small fourth-and-fifth-century pieces) are the most common ancient coins we see — usually in worn condition, often in lots of dozens or hundreds. Most are modest in value; a small subset of better-preserved or rare-issue late bronzes carries real premium.

Byzantine coinage

The Roman Empire in the east survived another thousand years past the western collapse, and Byzantine coinage continues the Roman tradition through the fall of Constantinople in 1453. Major denominations:

• Solidus — the gold denomination, struck from Constantine I (c. 312 CE) through the early Byzantine period, later evolving into the histamenon and tetarteron.
• Semissis and tremissis — half- and third-solidus gold pieces.
• Miliaresion — silver denomination introduced in the 8th century.
• Follis — bronze, continued from late-Roman practice, with large multi-letter denomination marks (M = 40 nummi).

Byzantine gold solidi are reliably valuable across all periods; the silver miliaresia from the iconoclast period have particular collector interest. Bronze folles from the major reforms (Anastasius, Justinian, the Heraclian dynasty) are well-collected at modest prices.

Other ancient categories

• Carthaginian — coinage from Punic Carthage, including the gold and silver pieces struck for the Punic Wars. Rare and valued.
• Parthian and Sassanid — the major Iranian empires of the Hellenistic-through-late-antique period, with distinctive silver drachms and tetradrachms.
• Indo-Greek and Kushan — Hellenistic successor states in modern Afghanistan and Pakistan; striking portraits and complex inscriptions.
• Indian punch-marked silver — the earliest Indian coinage, predating Greek styles in the subcontinent.
• Chinese cash coins — the round-with-square-hole bronzes were struck for over two thousand years. Most common dynasty pieces are modest; certain dynasties and specific issues are valued.
• Judaean coinage — including the Bar Kochba revolt, First Jewish Revolt, and Hasmonean dynasty issues. Strong collector demand for specific issues.

Authentication and provenance

These are the two issues that matter most for ancient coins, and they're the reason ancient-coin evaluation is fundamentally a hands-on process.

Authentication is harder for ancients than for modern coins because there are no published mintmark catalogs and no certificates of authenticity from the issuing authority. Authentication rests on:

• Physical fabric — correct weight range for the denomination, correct flan shape and edge characteristics for the period, correct metal alloy.
• Surface patina — genuine ancient patinas have structural depth and color complexity that modern fakes consistently fail to reproduce.
• Die style — the engraving conventions of each period and mint are documented. Counterfeits typically betray themselves through anachronistic style choices.
• Wear patterns — genuine circulation wear has specific characteristics that artificial aging doesn't reproduce.
• Surviving die corpus — for many important Greek issues, every known die is catalogued in the scholarly literature. A piece struck from an unknown die warrants extra scrutiny.

Provenance — documentation of the coin's history in the market — matters for high-value pieces. Auction-house records, dealer envelopes from earlier sales, old collection tags, and pre-1970 photographs all add value to a high-end ancient coin. The cultural-property concerns that drive the modern provenance requirement are real and increasing; pieces that can be documented as being in the market before recent dates have better long-term resale.

Most everyday ancient coinage doesn't have or need provenance paperwork. For modest-value pieces, the absence of documentation doesn't affect the offer.

NEVER clean an ancient coin

This rule applies more sharply to ancient coins than to any other category we evaluate. The patina on a bronze Roman sestertius is not dirt — it's part of the coin, and a meaningful part of its value. Stripping the patina to expose “clean” metal destroys the visual character that makes ancient coins desirable and reduces the piece to its metal weight (which, for a bronze, is almost nothing). The damage is permanent.

This includes:

• No chemical baths (lemon juice, vinegar, electrolysis, commercial coin cleaners).
• No mechanical scrubbing or wire brushing.
• No “just wiping it with a soft cloth” — even soft cloth abrades ancient patina.
• No olive oil soaks (a once-recommended method that still circulates in collector lore; we recommend against it).

If your coin is dirty or encrusted, leave it that way and bring it in. Professional conservation of ancient coins is a specialized craft we can refer for when needed; amateur cleaning is the single most expensive mistake an ancient-coin seller can make.

Why we can't quote ancient coins over the phone

Ancient coins require physical inspection more fundamentally than any other category we evaluate. Phone quotes simply can't be honest for raw ancients. Why:

• Attribution requires identifying the issuer, date, mint, and denomination from the design and inscription. Many ancient coins are illegible or partially legible; identification depends on style, fabric, and surviving details that don't come through a phone description.
• Surface condition drives value to an unusual degree. The same Roman denarius can be worth a fraction of its melt value in poor condition or many multiples in exceptional condition.
• Authentication is necessary before any meaningful price. We don't make offers on pieces we haven't authenticated.

The exception: coins already in slabs from NGC Ancients or a similar certified service. With grade and attribution fixed and visible on the holder, we can talk ballpark.

Why local matters for ancient coins

All the reasons local matters for other categories apply with particular force here:

• Authentication is the entire game. Online buyers can't authenticate ancient coins from photos with the same confidence as in-person evaluators. Their offers reflect that uncertainty — usually downward.
• Shipping risk is higher. Ancient coins are often fragile (oxidized bronzes can be brittle), and irreplaceable historical objects. The transit risk for a meaningful ancient coin lot is real.
• Privacy matters more. Ancient coins are increasingly scrutinized under cultural-property frameworks. A digital record of who sold what, when, and to whom is data that lives indefinitely; an in-person transaction creates only the record Oregon law requires.
• The relationship multiplies in value. Ancient-coin collections grow over years. The shop you trust with your first piece is the one you'll bring the rest of the collection to.

We've been buying ancient coins from Rogue Valley estates and collectors since 1997. We've seen Greek, Roman, Byzantine, and other ancient material at every price level. We're not here to dismiss online ancient-coin platforms — there are good ones — but for unauthenticated, raw, or hard-to-identify pieces, in-person evaluation serves the seller better in almost every case.

What to bring to your appointment

• The coins. As you have them. Loose, in flips, in albums, in old envelopes, in uncleaned lots. Don't separate or pre-sort.
• Any documentation — old auction records, dealer envelopes, collection tags, hand-written inventories from a relative who collected. All of this helps with attribution and provenance.
• Original storage — album, tray, or box. Sometimes provides clues about provenance that the coins themselves don't carry.
• Photo ID. Oregon requires it for precious-metals transactions, and ancient gold and silver fall under the same documentation requirements.

You don't need to identify the coins, look up references, or guess at attribution. That's exactly what we're set up to do.

Quick recap before you come in

In short, here's everything we just covered:

• Ancient coins are priced on attribution, condition, and patina — not metal weight. The math runs differently from US coins, world coins, or bullion.
• Most pieces are modest, a small subset is significant. Common late-Roman bronzes and worn Byzantine follis sell at modest per-piece prices; high-grade Greek silver, Lydian electrum, important Roman gold, and finest-known Byzantine solidi carry real value.
• Never clean an ancient coin. The patina is part of the coin and a meaningful part of its value. Cleaning destroys that, permanently.
• Authentication and provenance matter most, and both require physical inspection. We don't offer on pieces we haven't authenticated.
• Phone quotes aren't honest for raw ancients. Slabbed pieces with fixed grade and attribution are the one phone-friendly exception.
• Local matters with particular force here. Authentication, transit risk, privacy, and relationship all compound. A 28-year local reputation is structurally hard to replicate online.

That's the playbook. We'll go through every piece individually, authenticate it, explain what it is and what the offer reflects, and give you a number. You're free to accept it, decline it, or sleep on it — there's no fee for the evaluation either way.
