i live on a farm and we look for arrowheads in our corn fields. we were walking through the fields yesterday and my wife found this coin. i can make out what i believe is FR and a crown above it. i dont know what it is made of and dont know how to clean it. the other side is covered in green and i cant make out anything. it is a little larger than a pennie. any help on what it is and how to clean it would be great. the is a small shinny part and it looks like it could b copper or brass, but its so small i cant tell. thanks for any help!!!!

I have seen them before. Sure it's not a button? There were late 18th century military buttons with a similar device on them. If I remember correctly they were Spanish or Germanic.

from Coins from the Kings of France looks close but not quite. But it could be a button too.

There is a couple buttons HERE that look similar.

I think it might be a 1700s pfennig from Prussia. Great find!

Pfennig (guter) 1740-1786 Friedrich II Germany

sorry for the poor pic. my 1st time on a forum. thank you for all your help. the pic does not show the detail well but it is round. and thank you Bramblefind. that is exactly what it is. i have been searching four hours and hours looking at pics of coins and the last hour at buttons. weather it was a coin or a button i
have been happy either way. just glad my wife didnt through it back down after seeing it wasnt an indian artifact. lol. thank you once again!!!!!!!!!!!
