My my, this one is large…
United Kingdom, 2 shillings, 1965 (KM #906)
In the pre-decimal days, this coin was worth 2/20ths of a pound, the equivalent of 10 decimal pence. The “new” 10 pence coin introduced in 1968 was sized to match the old 2 shilling coin so that the old ones could circulate alongside their decimal equivalents. I wonder if this happened as intended. Anyway, when the 10-pence coin was reduced in diameter in 1992, it made the issue moot.
The reverse design combines all four emblem plants of the UK’s constituent realms… the English rose, the Scottish thistle, the Welsh leek, and the (Northern) Irish shamrock. It does so in a wonderful radial symmetry here. I think coin designs are at their best when they take advantage of radial symmetry.
