Silver Twentieth-Ounce (1/20 oz), Coin Type from United Kingdom - detailed information

Britannia coins are British bullion coins issued by the Royal Mint in gold since 1987 and in silver since 1997.

The original Britannia silver coins contain one troy ounce (1 oz) of silver and have a face value of £2. Silver Britannias are also issued in fractional sizes of one-half, one-quarter, one-tenth, 1/20th and 1/40th of a troy ounce and with face values of £1, 50p, 20p, 10p and 5p respectively (that is, the twentieth-ounce silver piece is officially denominated as 10 pence). There are also sizes larger than an ounce.

Being a tiny coin, the twentieth-ounce is not very practical as a bullion coin on its own, and is issued in proof mint sets only.
