Quick answer
A 1997 50p coin is usually the small Britannia 50p, worth face value to about £3. The Royal Mint struck 456,364,100 of them, the highest figure in its 50p mintage table. The large 1997 50p was not issued for circulation: it came in collector sets, and large coins of that type sell for roughly £5 to £20 uncirculated.

Why are there two sizes of 1997 50p?
1997 is the year the 50p shrank. The Royal Mint introduced the smaller coin on 1 September 1997, and for a short period both sizes were valid money.
The reason was practical. The 5p had been made smaller in 1990 and the 10p in 1992, which left the 50p as the largest and heaviest coin in everyday use. The Royal Mint says this revealed a requirement for a smaller 50p.
The new coin kept everything recognisable about the old one: the seven-sided shape, Christopher Ironside's seated Britannia and Raphael Maklouf's portrait of the Queen. Only the size changed.
| Large 50p | Small 50p | |
|---|---|---|
| In use | October 1969 to 1998 | 1 September 1997 to today |
| Diameter | 30.0mm | 27.3mm |
| Weight | 13.5g | 8.00g |
| Thickness | 2.5mm | 1.78mm |
The weight fell by about 40 per cent. If you have a 1997 50p and are not sure which it is, a ruler settles it at once: the large coin is 30mm across, the small one a little over 27mm. The coin diameter identifier and coin weight identifier will confirm it.
How much is the small 1997 50p worth?
The small 1997 Britannia 50p is the coin almost everyone has. It is worth 50p in a shop and only a little more to a collector.
MyCoinage tracked 36 verified sales:
| Condition | Sales | Sold price range | 90 day median |
|---|---|---|---|
| Circulated | 8 | 53p to £6.52 | £2.99 |
| Uncirculated | 4 | £3.99 to £6.52 | £6.52 |
| Brilliant Uncirculated | 21 | £2.25 to £20.00 | £4.21 |
Notice that most recorded sales are uncirculated coins. That is typical for very common dates: nobody bothers to sell a worn one, so the few circulated sales that exist are the better examples and include postage. A scuffed 1997 50p from your change is a 50p.
Why is the 1997 50p coin said to be valuable today?
It is not, and the mintage shows why. At 456,364,100, the 1997 small 50p is the most heavily produced 50p the Royal Mint lists. The next highest, the first 50p of 1969, is 188,400,000.
The figure reflects the changeover. The small coin had to replace every large 50p then in use, because the old size was about to be withdrawn.
Headlines and listings that claim a 1997 50p is worth hundreds of pounds are quoting asking prices, not sales. The guide to rare 50p coins shows which dates genuinely carry a premium.
How much is the large 1997 50p worth?
The Royal Mint's circulation table gives only one figure for 1997, and it belongs to the small coin. Large 50p coins dated 1997 were made for that year's collector sets and were not put into change. MyCoinage lists 109,557 for the large type that year.
Because they came from sets, large 1997 coins are normally found in uncirculated condition. MyCoinage tracks the large Maklouf-portrait 50p as one type covering 1985 to 1997, so its prices are pooled across those years, not specific to 1997:
- Brilliant Uncirculated: £5.00 to £21.49 (7 sales)
- Circulated: £1.76 to £12.18 (3 sales)
- Proof: £12.93 to £13.63 (2 sales)
That is 16 sales in total, so treat the range as a guide.
Silver proof versions
The Royal Mint also marked the change with silver versions for collectors. The 1997 small 50p silver proof is listed on MyCoinage with a mintage of 11,936, and six tracked proof sales ran from £29.95 to £52.69.
A silver proof is easy to tell from a circulation coin: it has a mirror finish, comes in a case or capsule, and was never in anyone's change.
Is the large 1997 50p still legal tender?
No. The Royal Mint states that the original larger 50p was demonetised in 1998. MyCoinage and standard catalogues give the date as 28 February 1998.
That applies to every large 50p from 1969 onwards, not only 1997. Shops do not have to accept them, and banks are under no obligation to take coins that are no longer legal tender. Policies differ, so ask your branch first.
The small 1997 50p is unaffected. It is the same size as today's 50p and remains legal tender, which the Royal Mint defines for the 50p as valid for payments up to £10.
Is there a 1997 50p error coin?
There is no documented 1997 50p error. The two sizes are the usual source of confusion: a large and a small coin with the same date and design look like a mistake when placed side by side, but both are official issues.
Other things that get described as errors on this date are ordinary:
- Differences in colour or brightness, caused by handling and storage.
- Slightly soft detail in the design, which is normal variation across a run of hundreds of millions.
- Edge knocks and flat spots from decades in tills and coin machines.
None of these adds value.
The Isle of Man 1997 TT 50p
Searches for a valuable 1997 50p often lead to a different coin entirely: the Isle of Man 50p issued for the Tourist Trophy motorcycle races. It shows two racing motorcyclists and was struck by the Pobjoy Mint, not the Royal Mint.
Like the UK coin, it straddles the size change. MyCoinage catalogues a larger TT 50p dated 1996 to 1997 and a reduced size one dated 1997.
It can sell for far more than the UK 1997 50p. Manx Radio reported in October 2024 that a 1997 Isle of Man TT 50p sold for £218 in an online auction.
Manx coins are not legal tender in the UK, so one found in British change is a collector's item, not spending money. The Isle of Man coins guide covers the series.
How to check your 1997 50p
Work through it in this order:
- Measure it. About 27mm means the common small coin. 30mm means the large type.
- Look at the reverse. Britannia seated with a lion is the UK coin. Motorcycles mean Isle of Man.
- Judge the condition. Only bright, unmarked coins sell for more than a pound or two.
- Compare against real sold prices using the coin value checker guide.
For the story of how the coin reached this point, see the history of the British 50p coin.
If you check your change regularly, log the coin in the Change Hunter on MyCoinage, which is free to start. It keeps a running value for everything you find, so a common 1997 50p sits alongside the scarcer designs you pick up later.
FAQ
Is a 1997 50p worth anything?
A small 1997 50p is worth its 50p face value, or up to about £3 in clean condition, based on sold prices tracked by MyCoinage in late 2026. With 456,364,100 struck it is the most common 50p the Royal Mint lists. The large 1997 50p from collector sets is worth more.
Why are there two sizes of 1997 50p?
Because the 50p was made smaller that year. The Royal Mint introduced the 27.3mm, 8.00g coin on 1 September 1997 to replace the original 30mm, 13.5g coin, which had become the largest coin in circulation after the 5p and 10p were reduced.
Is the large 1997 50p still legal tender?
No. The Royal Mint says the larger 50p was demonetised in 1998, with 28 February 1998 the date given in catalogues. It cannot be spent. The small 1997 50p is still legal tender and can be used like any modern 50p.
How can I tell if my 1997 50p is the large or small one?
Measure across the coin. The small 1997 50p is 27.3mm wide and weighs 8.00g. The large one is 30.0mm and 13.5g, noticeably heavier in the hand. Both show Britannia and the same portrait of the Queen.
Is there a rare 1997 50p error?
No documented 1997 50p error exists. The large and small coins of the same date are both official. Marks, colour differences and weak detail come from wear and normal production variation and do not make a coin more valuable.
What is the 1997 Isle of Man TT 50p worth?
It is worth far more than the UK coin. Manx Radio reported a 1997 Isle of Man TT 50p selling for £218 in an online auction in October 2024. It is a Pobjoy Mint coin showing racing motorcyclists and is not legal tender in the UK.
