This coin is one sided. You can see the reverse impresion on the back side. If I can figure out how to post pictures I will. I'm a newbie. Thanks for any info i fihufig it out. This is front and back of coin.
Appears to be a British farthing, maybe a canadian cent. weight would be important. I once had what appeared to be a full brockage farthing like that but the weight was too light. I suspect it was some type of embossed decoration, maybe the cover for a button. If the wight matches that of an actual coin then you've probably got something.
