hard to say, trying to work on a method for picking them. namly, curculation life of a coin (ease of wear etc, how often a coin is used day to day) the mintages, and events of the year (people saving coins of that year etc) still hard to find anything except the usual 1992 dot to dot 10p and small head 1992 20p there is very little in general coinage 1992-97 20ps never seem to wear lol pennies and 2p's usage is low IMO (getting common to find 90's copper with some lustre) 5p? i dunno tbh. 10p, 2008 old design and dot to dot. but mainly nothing there 20p, a few noted ones, but hard wearing is in a issue for saving the higher grades 50p, not much post 97 to get excited about £1. this is the way to go, high curculation life (or easy wearing) with a couple of nicer dates (1988 and 2008 old design) £2. low mintage but probably kept back more oftendue to designs, but plenty here to save. its not as fun as back then i admit lol boring years are the way to go
