DAS, (Hello, I assume you are the same DAS that has been a good customer these last few weeks!) An Evasion Halfpenny, or an evasion anything for that matter is a counterfeit coin, deliberately made to differ enough from the real thing to avoid being illegal. I would imagine some of the British fake George III half pennies with legends like 'George III Rules' and so on, could be described as such. The maker could claim that they are commemorative or token coins in celebration of the king, when really at that time when poor people couldn't read all that well, they could also be readily passed off as the real thing, but with little risk of prosecution for the maker. I think I probably have a few Evasion halfpennies and most seem to be from the reign of George III. Another example given in this years coin yearbook is the imitation Sumatran coins by European merchants that were inscribed SULTANA instead of SUMATRA! Chris www.predecimal.com
