Out of interest, the 53 halfcrown isn't one of the ones broken out of the plastic sets, it's an Obverse 2 made for circulation. Commoner on issue, but as more of the plastic sets got broken up, and as Obv 2s got more circulation, I'm sure that high grade examples have become scarcer than Obv 1s now. Thanks for the info,very helpful it is in quite good condition i think,i'm pretty sure i will be keeping that one.
