Error Planchet | Clipped Planchet or 'Tom Foolerey'

[Guest]

I was wondering if there is a definitive way to tell the difference between a genuine clipped planchet error and a coin that has been altered after it left the mint?

Thanks in advance;

I would say the 55 is PMD.

You have post mint damage.
When looking at an incomplete planchet error it should have what is known as the Blakesley effect. Most of the time. the area of the rim 180 degrees opposite the "clip" is weak or nonexistent since the "clip" impairs the rim-making process. The lack of pressure at the missing spot results in improper formation of the rim on the opposite side.
Also, there should not be any raised metal in the area of the clip. This indicates the area being sheared PMD.

Definitely schenanigans. Perhaps a couple of Jason's hooligans were responsible. Without a doubt, the work of no-good-nicks.

That poor coin...looks like a slice of pizza was taken out of it!

Ha! Hooligans on parade...apparently my hooligans!

Definitely post strike damage... I can tell because of the letters... They are stretched in the direction of the cutting... Still good conversation pieces!!!

There are four indicators of a genuine clip; 1) Blakesley effect at the pole opposite the clip; 2) taper and fadeout of the design rim as it approaches the clip; 3) metal flow in design elements adjacent to the clip; 4) a cut-and-tear texture on the clipped edge.

Mike, a couple of quick questions please.
3) metal flow in design elements adjacent to the clip.....the metal flow would increase to the elements adjacent to the clip, correct? And if that is correct, then what would that look like? Bolder, fatter, etc?
also, I don't understand number 4. What does a cut and tear texture on the clipped edge look like?
Thanks for helping me understand this better.
