How Florin House values coins

• Numista catalogue — an estimate from Numista, the collectors' online catalogue, for this coin. More
• Numista type value — Numista's estimate for another issue of the same design (another year, or another strike of it), not for this one. More
• Silver price, Gold price — the melt value: what the metal in the coin is worth. More
• Price-guide figure — a figure entered from a UK price guide in 2025. More
• Collector submission — a figure a collector sent us, accepted by an administrator. More

Where a coin has none of these, its value box shows a dash rather than a number. Where all we know is its metal and the metal cannot be priced, it adds “No catalogue price recorded”.

Numista is a catalogue of the world's coins kept by collectors, and it publishes price estimates for many of them, grade by grade. When we import a coin from Numista we ask for its estimate in pounds and record the date we asked. That date is the one shown beside the figure.

Numista quotes a price for each grade it has data for. Where a coin page names the grade — Numista catalogue, Very Fine — the figure is the estimate for that coin's own issue in that grade, unless the page calls it a type value: since 26 September 2026 a type value names the grade it was quoted at too (Numista type value, Very Fine). Where it does not, the figure came from an earlier import that did not record the grade: it is the Very Fine price where Numista gave one, and otherwise the first it gave of Fine, Extremely Fine, Very Good, About Uncirculated, Good and Uncirculated.

Numista groups coins into types: one design, often struck for many years. When our importer brings in a type it asks Numista for one price: for the issue you added, or else the one with the largest recorded mintage. It gives that price only to the type's other issues of the same strike (circulation, brilliant uncirculated or proof), and names the grade it was quoted at. Coins brought in before 26 September 2026 were priced twice at most, once for circulation coins and once for brilliant uncirculated and proof together, and their pages say which strike the price was for.

A coin page whose figure came that way says Type value, with a note that its year has not been priced separately — or, where another issue of the same year does have its own price, that this issue has not. Where brilliant uncirculated and proof coins were priced together, a proof's type value is often the price of a brilliant uncirculated issue, and the other way round; the page then says which strike the price was for (BU price).

Read a type value as the going rate for the design, not for that year or that strike: a scarce year of a long-running type, or a proof, can be worth many times the type value. Where an issue has since been priced on its own, its page gives the figure as that issue's estimate, not a type value.

A melt value is what the metal in a coin is worth: its weight, times the fineness its composition states, times the price per gram of silver, gold or platinum, in pounds. A coin page shows it in two cases: when it is higher than the catalogue figure (an old silver coin is never worth less than its silver), and when the coin has no catalogue price at all, where the page adds “No catalogue price recorded”.

The date beside a melt value is the day the metal prices were last fetched. If they cannot be fetched, the page says it is using reference prices from March 2026 instead. We only price metal whose fineness is stated. Billon, a composition given only as “silver”, plated, clad or gilt coins, and look-alike alloys such as Nordic gold and nickel silver are not priced, and a coin with nothing else to go on then shows no value.

Several hundred pages, most of them modern UK commemorative coins, carry a figure entered by hand in June and July 2025, when the catalogue was first built. The scripts that entered them credit UK collector price guides, chiefly Coin Hunter's. They are labelled Price-guide figure with the month they were entered, and they have not been updated since: read them as a dated guide price, not today's market.

A Collector submission is a figure a collector sent us with a coin they added to the catalogue. Submissions wait until an administrator accepts them; the date is the day the coin was accepted. A figure whose source was never recorded says so.

The month beside a figure is when that figure was recorded — the day we asked Numista, the day a price guide figure was entered, the day a metal price was fetched. It is never the date of a sale. Some figures are more than a year old; the date is there so you can judge that for yourself.

A catalogue figure describes a typical example in one grade, and the importer takes Numista's Very Fine price where there is one: a coin that has circulated, with light wear on the high points. A more worn coin is usually worth less; an uncirculated one, or a proof in its case, more. Brilliant uncirculated and proof versions have their own pages, because they are sold as different things. Many have a figure of their own; where one carries a type value priced for the other strike, its page says so (see type values).

The score out of 10 comes from the coin's mintage — how many were struck. Every three months each coin with a recorded mintage is ranked against every other one in the catalogue: the lowest mintages score 10 and the highest 1. A coin added between rankings is scored from fixed bands until the next one (500 or fewer struck scores 10; more than 100 million scores 1).

Three adjustments follow:

• a coin from before 1900 gains a point, and one from before 1800 two, because far fewer old coins survive;
• brilliant uncirculated and proof coins from 1990 on are held at 7 unless their catalogue price says they are scarcer, because collector editions are made in small numbers on purpose;
• where the coin's recorded price strongly disagrees with its score, the score moves up to two points towards what the price suggests.

A coin with no recorded mintage is not rated: its page says so, and shows no score.

The mintages of the UK decimal coins entered in 2025 came from collector references, chiefly Change Checker and Coin Hunter. Coins imported from Numista carry Numista's figure for that issue. Not every figure has yet been checked against the Royal Mint's published mintages, and some are known to be wrong, so treat a mintage that looks out of line with care, and tell us if you know the right one. A mintage can also be missing, because not every issue was counted.
