The type set I want to do for British coins is Victoria to Elizabeth pre decimal. That means I'd get a half penny, penny, farthing, 2 pence, 3 pence, 4 pence, 6 pence, shilling, florin, half crown and crown for Victoria, Edward vii, George v, George vi, and Elizabeth Ii. I'd also do varieties like 90% silver and 50% and copper nickel for George v coinage and so on and so forth.
