How Much Is a Roman Coin Worth?
Short answer: most Roman coins in circulation among collectors are worth between £10 and £150. Late Roman bronzes start at a few pounds, mid-grade silver denarii sit in the £40–150 band, attractive sestertii run from a few hundred to a few thousand, and gold begins around £2,500. Coins worth five and six figures exist but are a vanishingly small fraction of what survives.
The gap between what people expect a two-thousand-year-old coin to be worth and what it actually fetches is the single biggest source of confusion in ancient numismatics. The reason is simple: Rome minted staggering quantities of coin, buried hoards preserved them, and modern discovery has put hundreds of thousands of genuine examples onto the market (Harl, 1996; Abdy, 2002). Scarcity, not age, is what you are paying for.
The five things that set the price
- Rarity of the exact type. Not "how rare are Roman coins" but how rare is this obverse and reverse combination from this mint in this year. Standard references assign rarity ratings for exactly this purpose (Mattingly et al., 1923–1994).
- Grade and eye appeal. Two coins of the same type can differ in price by a factor of fifty on condition alone. And eye appeal is separate from grade: centring, surface quality, patina colour and strike sharpness all move the number.
- Metal. Gold carries a floor from its bullion content that silver and bronze do not.
- Who is on it. Demand is wildly uneven. Julius Caesar, Augustus, Nero, Hadrian, Marcus Aurelius and Constantine command premiums driven by name recognition rather than by scarcity.
- Provenance. A documented ownership history — an old collection, a published sale, a pre-1970 record (UNESCO, 1970) — adds real money and, for higher-value coins, is increasingly a condition of sale.
Indicative price bands
The figures below reflect the range of realised auction and retail prices observed as of August 2026, for genuine, unproblematic coins. Treat them as orientation, not appraisal — the spread within any single row is driven by the type and the eye appeal.
| What you have | Worn / Fine | Very Fine | Extremely Fine |
|---|---|---|---|
| Late Roman bronze AE3/AE4 (Constantine dynasty) | £3–15 | £20–60 | £70–200 |
| Antoninianus, common 3rd-century emperor | £10–25 | £30–90 | £100–300 |
| Denarius, Severan (Septimius Severus, Julia Domna, Caracalla) | £40–80 | £90–250 | £300–700 |
| Denarius, 2nd century (Trajan, Hadrian, Antoninus Pius) | £50–120 | £130–350 | £400–1,000 |
| Denarius, early imperial (Augustus, Tiberius, Twelve Caesars) | £150–400 | £400–1,200 | £1,500–6,000 |
| Republican denarius, common moneyer | £40–100 | £110–300 | £350–1,200 |
| As or dupondius | £25–70 | £80–250 | £300–900 |
| Sestertius, common emperor | £50–150 | £250–1,200 | £1,500–8,000 |
| Aureus, common emperor | £1,800–3,000 | £3,000–7,000 | £8,000–25,000 |
| Solidus, 4th–5th century | £600–1,000 | £1,000–2,500 | £2,500–7,000 |
Why a rare emperor is not automatically expensive
New collectors reasonably assume that an emperor who ruled for three months must produce rarer coins than one who ruled for twenty years. Sometimes true, often not. What governs survival is how much was struck and where, and a short-reigned emperor who controlled a productive mint could leave more coins behind than a long-reigned one who did not.
The reverse effect matters more. Demand concentrates on names people recognise, so a coin of Hadrian in the same grade as a coin of an obscure contemporary will frequently cost more despite being commoner. Collectors who buy on genuine scarcity rather than on name recognition get considerably more for their money.
How to check a real price in ten minutes
You do not need to guess, and you should not rely on asking prices, which are aspirational. Sold prices are what matter.
- Identify the type first. You cannot price a coin you have not identified, and the free index maintained by the American Numismatic Society (no date) is the quickest route to a reference number — see our six-step identification guide.
- Search auction archives for the emperor plus the reverse type or catalogue number. Public archives of past sales let you filter to results that actually sold.
- Filter to matching grade. Compare against coins in the same condition, not the best example on the page.
- Read the hammer price, then add the premium. The buyer pays hammer plus a buyer's premium, commonly around 20–25 per cent, plus shipping and sometimes import VAT. A £100 hammer costs roughly £125–135 delivered.
- Take the median of five or six comparable results, not the highest.
Retail, auction, and what you can actually sell for
There are three different numbers attached to any coin and confusing them causes most disputes.
| Number | Roughly | What it means |
|---|---|---|
| Dealer retail | 100% | What you pay a dealer, including their guarantee and their time |
| Auction hammer | 60–85% of retail | What the market pays on the day, before premium |
| Dealer buy price | 30–60% of retail | What a dealer pays you for stock |
| Insurance / replacement value | 110–130% of retail | What it would cost to replace, used for cover, not for sale |
What destroys value
- Cleaning and polishing. The fastest way to halve a price (Scott, 2002). See why cleaning almost always costs you money.
- Tooling and smoothing. Modern re-engraving. Detected by specialists, and heavily penalised.
- Holes, mounts and scratches. A hole for suspension typically removes 50–80 per cent of value.
- Active bronze disease. Untreated chloride corrosion is progressive and makes a coin unsaleable until stabilised.
- No provenance at the top end. Below a few hundred pounds this rarely bites. Above a few thousand, an undocumented coin is worth materially less than a documented one, and may be unsaleable at major houses.
A realistic expectation for an inherited collection
Most inherited groups of Roman coins turn out to be a few dozen bronzes and a handful of silver, with a total value in the low hundreds. That is not a disappointing outcome so much as an accurate one, and it is worth knowing before you pay for a formal appraisal. The exceptions — a gold coin, an early imperial silver piece, or anything with old collection tickets attached — are exactly the things worth having looked at properly, because old tickets are provenance and provenance is money.
Frequently asked questions
How much is a Roman denarius worth today?
A common denarius of a 2nd or early 3rd century emperor in collectable condition typically sells for roughly 40 to 150 pounds. Attractive examples with full legends and good silver surfaces run from about 150 to 400 pounds. Early imperial denarii of Augustus, Tiberius or the Twelve Caesars start higher, commonly 300 pounds and up, and genuinely rare types run into thousands.
Is an old coin worth more than a newer one?
No. Age has almost nothing to do with value in ancient numismatics. Supply does. A 4th century bronze struck in the hundreds of millions is worth a few pounds while a 1st century BC denarius from a small issue can be worth thousands, and both are ancient. Value tracks how many survive, how many people want them, and what condition they are in.
Will a dealer pay me what my coin is listed for online?
No, and this is the most common disappointment in the hobby. A dealer buying for stock typically pays somewhere between 30 and 60 per cent of retail, because they carry the cost of authentication, photography, listing, guarantee and the time until it sells. Consigning to auction usually nets more but takes months and deducts a seller commission.
Does cleaning a Roman coin increase its value?
Almost never, and it very often destroys value. Original patina is part of what collectors pay for. Stripping it, polishing a coin, or scrubbing at it with abrasives can cut the market value of an otherwise good coin by half or more, and the damage cannot be undone.
