18th century halfpennies

Hi, I have these two 1775 George III halfpennies & I know standard (legal) & evasive (counterfeit) versions both circulated, but how can I tell the difference?

Looking at these two one looks much rougher than the other & it is slightly smaller & thinner.

Can anyone offer any advice, please.

​Sorry about that, my light levels indoors aren't the best. Hope these are clearer.
