| Additional information |
Guernsey's doubles denominations existed purely because the island refused to adopt British sterling as its everyday coinage — a stubbornness rooted in Norman customary law and reinforced by the States of Guernsey's jealously guarded fiscal autonomy. The double itself had no equivalent anywhere in the British monetary system, making these coins functionally useless the moment a Guernseyman crossed to the mainland.
The 47-year production run across this type masks significant gaps in striking — issues were placed with the Royal Mint only when local copper stocks ran low, not on any regular schedule.
