Points to Note

The Royal Mint have re sized the 5 p, 10 p & 50 p coins.
The 1/2 p is no longer in circulation
The £1 is deeper than a standard capsule so we prefer to use a 22 mm airtite rings for ours.
The Royal Mint have plans to change the design and size of the £1 coin in the near future.
These sizes are correct as of 2014.
