@paddyman98 has a video clip. My critique is that a spooned coins is "raw" in nature . A process of wacking the crap out of the rim of a coin until the side raise up . Get ready to be entertained . A spooned coin takes all of its damage on the rim with little collateral damage to the devices. Often the rim will be folded over onto the fields of each face. The differences are obvious; if the rim is thin with worn devices, it's a dryer coin; if the rim is thick with no wear on the devices, it's a spooned coin.
I was a spooner as a youngster. I didn’t have video gadgets so I amused myself...... You can start with a nickel (most popular)... Sit down and just start tapping with the back of a spoon. After a bit you can see the rim becoming upset. The longer you tap, the more the rim raises and the diameter of the coin gets smaller. You can drill the center and have a ring but I never did that.
There is a video on how to do that also. Some feel it's damaging coins by defacing them. I say if they are damage anyways, who the heck cares . Spoon away .
