How we value coins

For each design we collect every published UK figure we can find: price guides, dealer prices, auction results, sold-price reports and news reports of sold prices, preferring recent ones. Each is recorded with its source, whether it describes a circulated or an uncirculated coin, and when it was published. That comes to 3,499 published prices across 334 designs, last checked on 19 September 2026.

Circulated and uncirculated values are worked out separately, each from the prices for that condition.

1. One number per price. A price given as a range counts as its midpoint; a single price counts as itself.
2. Typical value. The median of those numbers.
3. Range. With 4 or more prices, the range runs from the 25th percentile of their low ends to the 75th percentile of their high ends. With fewer, it runs from the lowest price to the highest. That gives 134 circulated and 316 uncirculated values a percentile range, and 7 circulated and 14 uncirculated values a lowest-to-highest range.
4. Face value floor. No figure goes below the coin's face value.
5. Rounding. Each figure is rounded to whole pence under £1, to 10p steps under £5, to whole pounds under £100 and to £5 steps from £100 up. If rounding leaves the typical value outside the range, the range is widened to include it.
6. Face value only. When the sources agree that a circulated coin trades at or near its face value, its page says so instead of giving a circulated range. That applies to 58 designs.

Confidence follows the number of prices behind a value, taking whichever condition has more. One design has no published price and shows no value.

Rarity comes from mintage alone: the number of coins struck for circulation, from The Royal Mint's published figures, last read on 19 September 2026. A design struck in several years counts the total of those years.

Designs are ranked from the lowest mintage up, within each value and across every value on the list of rare UK coins. Designs with the same mintage share a rank, and the next rank skips. That ranks 194 designs. Another 136 were not issued for circulation and 5 have no published mintage; they are listed without a rank.

Each ranked design also falls in a rarity band set by fixed mintage cut-offs:

The coin photographs are The Royal Mint's, credited under each photo with the year. 309 of the 335 designs have one; the others show a drawing of the coin's outline with its name and year.
