Spinks 2012 Coin Book

Just reading through my latest coin book Spink 2012 and was interested to note in their preface that as from next year, it will be getting split up into two books. Decimal and Pre-Decimal. I know a lot of collectors who don't have an interest in later coinage, but there are a growing band, who like collecting the different commemorative issues and the different types of 50p. The prices might surprise some people. So check your change!!
