I got this in a lot of 75/100 Colonial tokens and large cents for a dollar or two each, 10 to 15 years ago. I threw it into the junk pile and took care of business with the other coins.
Later, I was going to sell it off in a lot of crappy coins until I had a look at the other side and thought it was too strange to get rid of. I had thought it was just a banged up coin, but with a second look, both sides still have a raised rim, and one side looked too good for the token to have been beaten so much.
It weighs 7.84 grams and is 29.5 mm wide (my 5 other LC-5A's are 8.18 to 8.40 gms. and 28 mm.). It is thinner than the others but is larger in diameter so it has obviously been flattened.
Most of the "UN SOU" side is slightly raised, with a deep groove on the left. The higher parts slope down to a very narrow raised rim (much wider at the top of the token).
The "bouquet" side is lower than the rim. The rim slopes down for a bit and then the field rises slightly again and is flat.There is a remnant of the letters of "AGRICULTURE" remaining at 10:30 to 11:30 on the bouquet side. They look overlapped as if struck more than once.
I can't see how the rims and bouquet side would be so smooth and unmarked if this was just the result of being hammered somehow. Is it possibly an old die cap ?
