Geo III 1/2p - Blacksmith Or Garbage ?

Yes, it does have post-mint damage. Now you can't just mark that to add another post to your totals.

I have about 50 Geo III farthings and halfpennies between 1771 and 1775. Many are counterfeits and vary in quality. If this coin didn't have the strange raised metal lines, I would have just thought it was a very worn, long buried, corroded coin, maybe acid-soaked. But those lines look to be as old as the coin. And it doesn't look like it really ever was a decent-looking fake or original 1/2p. Some blacksmith tokens do have a similarity.

All black but silvery where it's worn, non-magnetic. It's 27 mm, 1 mm. smaller than a 1/2p should be, and it weighs less than half the weight of a real 1/2p. In the pile of stacked coins; bottom, 8.4 gms counterfeit Geo.III 1/2p, middle, 6.2 gm. counterfeit Geo. III 1/2p, top, coin in question, 4.3 gm. The edge is extremely thin, between butter knife and steak knife. The images and letters are clearly raised, as well as the strange lines.

Were those lines made because someone tried to make a fake with rusty, broken dies on a lousy planchet ? Something melted onto it ? Would those lines happen as it was corroded or put in acid ? Beat's me.
