25 Pence - Elizabeth II Remembrance Day

Alderney, a self-governing dependency of Guernsey, has issued commemorative crowns and fractional pieces under its own authority since 1993, though all carry the legal tender status of the Bailiwick. This 9-carat piece sits at the lower boundary of what British hallmarking law defines as gold — .375 fineness — making it a deliberate cost-reduction choice to keep a bullion-adjacent commemorative accessible at retail price points without straying into base-metal territory.

At 1 gram, the gold content is fractional by any measure: approximately 0.375 grams of fine gold per coin.
