 to CCF. That is an incomplete planchet error,nice. The dark lines running across it is cool looking also. Wonder if it is roller lines or an alloy mixture error? John1  |

Nice. Clipped planchet. As far as value goes, it depends on the Polish colletcor market. A similar US coin would be worth $5-$10 IMO. I couldn't say what a Polish one would sell for

Definitely a legit error... the rims dovetail in nicely. to CCF!!

The striations appear to be a plate stock extrusion fault (rolling flat) the metal was too cold when pressed.Note also the weakness of the rim on the opposite side of the clip. Happened in the "Blanking" process when first punched out of a stock metal sheet.

Note also the weakness of the rim on the opposite side of the clip. Happened in the "Blanking" process when first punched out of a stock metal sheet. This happens in the rolling mill stage, which turns blanks into rimmed planchets. This is done by having the blanks fed into a grooved wheel that then applies force to the rim of the blank. A clip in the blank causes a drop in pressure on the opposite of the coin - Newton's Third Law.
