British & English Copper Coin collecting

GEORGE II Halfpenny Defective 3 in date resembles a 5

We know is a three as its a young head halfpenny and not the older or obverse 2 portrait of George II , but i have seen them sell as 1756 and dies more advanced in deterioration do look more like a 5. This coins in a intermediate between stage and could be a 3 or 5 to an untrained eye. When a well established coin book ( you know who ) lists and values this coin as a 1756 you know the passions gone and its really is just an annual catalog to make money, how can a new collector learn participate and love a truly absorbing hobby with crap printed like that. Im glad to say it was removed after it was pointed out how silly they had been.  Halfpenny grades fine or slightly better.
