1773 Colonial Thought And Grade

Pics are a bit dark.

Looks to be a George III half penny, AG condition to me (and from the photo it looks like a 1775 to me). To be genuine it should be between 9.2-10.8g and 28.5-30mm. Contemporary counterfeits were a common thing especially on the 1775, the details definitely look a little off from a genuine piece, but colonial coins were rife with inconsistency.

Interesting. With a 20mm diameter it is more likely a farthing (normally ~23mm, 5g). It certainly looks like it is missing some metal around the edges, hence the smaller diameter, but that doesn't explain the extra 3g. Contemporary counterfeit is seeming more likely to me, but there can still be a market for those.

This is getting outside of my level of knowledge at this point though
