10p A-Z Coin Values: Great British Coin Hunt & Rare Date Guide
The 2018–2019 Great British Coin Hunt put 26 unique 10p designs into circulation, one per letter of the alphabet, and turned coin collecting into a national hobby. Beyond the A-Z series sits a longer story: a 1968 florin-sized large 10p, a 1992 size reduction, three reverse designs in 56 years, and the first Charles III 10p in 2023. This guide is the full 10p reference with mintages, values, authentication and selling advice.
A short history of the 10p
The decimal 10p was introduced on 14 October 1968, more than two years before Decimal Day. The Royal Mint deliberately matched its physical specifications to the pre-decimal florin (two shillings) — 28.5 mm in diameter, 11.31 g in weight, cupro-nickel (75% Cu / 25% Ni). This let both coins circulate side by side from 1968 to 1971 at the same value, smoothing the transition to decimalisation. After 15 February 1971 (Decimal Day), the florin was officially demonetised, but old florins continued to circulate as 10ps for some years until they were withdrawn through bank deposits.
On 30 September 1992 a smaller, lighter 10p was introduced — 24.5 mm and 6.5 g — in line with the wider Royal Mint programme to reduce the weight of UK silver-coloured coinage. The large-format 10p remained legal tender alongside the smaller coin until 30 June 1993, when it was finally demonetised. Many pre-1992 large 10ps survive in collector hands but cannot be spent or directly redeemed at retail banks.
Three distinct reverse designs have appeared on the 10p:
- Christopher Ironside crowned lion (1968–2008). A heraldic lion passant guardant beneath a Royal Crown, derived from the English royal arms.
- Matthew Dent Royal Shield (2008–present). The 10p forms the lower-left segment of a quartered Royal Shield, with the full design forming across the 1p, 2p, 5p, 10p, 20p and 50p denominations. The £1 carries the entire shield.
- A-Z Great British Coin Hunt (2018, 2019, brief 2023 re-issue). 26 letter designs by Edwina Ellis depicting Britishness from Angel of the North to Zebra Crossing.
The first Charles III obverse 10p appeared in 2023, with the Martin Jennings portrait. The reverse retained Dent\'s Royal Shield while new commemorative reverses are designed.

|---|---|---|---|---|
| Large 10p | 1968–1992 | 28.5 mm | 11.31 g | Cupro-nickel (75/25) |

The full A-Z 10p list with mintages
Designed by Edwina Ellis, each coin depicts something "quintessentially British" beginning with the letter shown. The 2018 series struck a uniform 2.6 million per letter for circulation. The 2019 re-issue, sold predominantly through Royal Mint completion packs and small-volume distribution, had variable per-letter mintages roughly an order of magnitude smaller.

A-Z 10p values and the most-sought letters
Because all 26 letters in the 2018 series were struck in equal numbers, demand drives prices rather than rarity. The most consistently requested letters are:
- X (X Marks the Spot) — the hardest letter to design and one of the wittiest pieces in the series. BU examples reliably sell at the top of the range.
- Z (Zebra Crossing) — the final letter of the alphabet and the one most often missing from a set assembled from change.
- Q (Queuing) — popular for its self-deprecating Britishness; reliably sought after by completists.
- K (King Arthur) and L (Loch Ness Monster) — popular for the design quality.
| Coin / format | Description | Typical realised range |
|---|---|---|
| Single A-Z 10p, circulated | Mid-range letter, found in change | £0.50 – £2 |
| Single A-Z 10p, EF | Lightly handled, full design | £3 – £5 |
| Single A-Z 10p, BU pack | In sealed Royal Mint card, with COA | £4 – £10 |
| X / Z / Q in BU | Top-demand letters, sealed Royal Mint pack | £8 – £15 |
| Complete 26-coin BU album | Royal Mint official album, all letters in BU | £120 – £200 |
| Complete 26-coin circulating | Mixed grade, found in change, in collector folder | £30 – £60 |
| 2019-dated single letter, BU | Lower mintage re-issue, harder to find | £6 – £15 |
Authenticating A-Z 10ps and "BU pack" claims
The A-Z series attracted significant secondary-market activity and a corresponding wave of misleading or outright fake listings. Three categories of issue dominate eBay:
- "BU pack" with no original packaging. The Royal Mint sold A-Z 10ps in individually heat-sealed plastic on coloured cards with a printed Certificate of Authenticity. A loose coin advertised as "BU" without the sealed pack is just a circulation coin in good condition. Pay only the circulating-grade price.
- Resealed packaging. Some sellers reseal opened packs with new shrinkwrap. Tells: the heat-shrink is loose around the corners, the COA card shows handling marks behind the plastic, the back of the card shows fingerprints, or the seal has visible vertical joins from a hand sealer rather than the Mint\'s factory seal.
- Altered or "letter swap" coins. Crude attempts to alter common 10p reverses into rare letters by milling or laser-engraving. Tells: irregular field around the letter, missing micro-detail in the surrounding design, weight outside the expected 6.50 g ± 0.05 g window, and an obverse that shows tooling near the alteration.
For high-value listings (notably the 2019-dated low-mintage letters in BU), buy only from sellers with a clear photograph of the original Royal Mint pack and a return policy. For the strictest authentication, send the coin to CGS UK or NGC before resale; the slabbed grade typically pays for itself.
Pre-A-Z 10p rare dates and varieties
Beyond the A-Z series, the 10p has a small number of dates worth picking out from change or from old Royal Mint Year Sets:
| Year | Type | Mintage | Typical BU value |
|---|---|---|---|
| 1968 | Large 10p, first year, Ironside lion | 336,143,250 | £3 – £6 |
| 1969 | Large 10p, Ironside lion | 314,008,000 | £3 – £5 |
| 1979 | Large 10p, Ironside lion | 115,457,000 | £2 – £4 |
| 1992 | Small 10p, first year of new size | 1,413,455,170 | £3 – £5 |
| 1992 | Large 10p, final year of large size | Proof only | £8 – £15 |
| 2008 | Small 10p, first Royal Shield | 71,447,000 | £3 – £5 |
| 2008 | Small 10p, last Ironside lion | 9,720,000 | £5 – £10 |
| 2023 | First Charles III 10p | ~10–15 million est. | £3 – £6 |
The 2008 dual-design year is the closest the 10p comes to a true "rare date" in the modern series. Both the final Ironside lion (low-mintage, transitional) and the first Royal Shield design were struck for circulation, with the Ironside the scarcer of the two. Original 2008 Royal Mint Year Sets contain both designs and trade for a small premium.
Grading thresholds for the 10p
Cupro-nickel survives circulation better than bronze, so 10ps grade harshly. Practical thresholds:
- Brilliant Uncirculated (BU / MS63–65). Full mint lustre, no contact marks visible to the naked eye. Almost always from a sealed Royal Mint pack or unopened year set.
- Extremely Fine (EF / AU50–55). Light wear on the highest design points only; full hair detail, full lion mane or shield definition, sharp legend.
- Very Fine (VF). Some wear on hair, mane and shield rim; design fully visible but no longer crisp.
- Fine and below. Worth face value; not worth grading or listing as collectable unless the coin is a verified rarity.

Where to sell A-Z and rare 10ps
The market for 10ps is dominated by the A-Z series and is largely retail rather than auction-driven. The right venue depends on the format:
- Single circulating A-Z letters: eBay UK auction format with sensible reserve. Selling fees approximately 13%.
- Sealed BU packs and complete albums: eBay and specialist Facebook coin-collector groups produce the strongest realisations. Provide clear photographs of all four edges of any sealed pack to confirm originality.
- Pre-1992 large 10p in EF or BU: small sums by single coin; consider bundling a date run and selling as a set, or trading in to a dealer such as Coincraft or Colin Cooper Coins.
- Verified mint errors and rarities: consign to a specialist British numismatic auction such as Baldwin's, Spink or Noonans.
