When googling or eBaying (click worldwide) British Commonwealth stamps Qyeen Victoria is sometimes abbreviated as QV and the denomination (one penny, 1 penny) is written as 1d where d = denarius = Roman silver penny = and thus terminology from a Roman province in the British Isles originally.
Also know as one penny and plural would be 2 pence, 3 pence 2-1/2 pence, etc, written abbreviated as 2d, 3d, 2-1/2d, etc.
Quite satisfyingly confusing I think.
