Bermuda 1.10.1966 P-19c PMG Gem UNC 66 EPQ 10/- Shillings
The 10 Shillings denomination is a bit underrated, especially in the best grades. 1966 is the final date for the type, as decimal notes replaced pounds and shillings in 1970. It also has the lowest print-run of any Queen Elizabeth II pre-decimal types.
