Went out for a couple hours today to hit a lot that had been cleaned last fall. A friend had found a few Wheaties & a 47 dime on the lot just the other day so I didn't think I would come up with much. I had found a few newer coins then got a solid 47 on the MXT. Down about 6" out popped a button looking thing, I didn't think much of it & kept on hunting. Got home for lunch and started to clean up the button to see what it was and here it is. I am guessing a cuff link but not sure, on the back the words Paten Dec. 2nd 8 the outer ring looks like brass but the W looks gold to me, anyone out there seen one of these, if so what is it.
