ok you might say, it's a clip or "cut" but this has a ragged edge and for SURE broken..never seen nothing like it in my 25 years of collecting:welcome:
A uniform, grainy edge is a pretty good indicator of a natural break. If a planchet breaks before the strike it's called a "broken planchet" error. If a coin breaks apart after the strike it's called a "broken coin". They are comparatively rare, far rarer than split planchets.
One would think that this could be easily replicated with freon, isobutane, or liquid nitrogen soft leather & a vise.
Although I've not tried to replicate any of these scenarios, I suspect you're correct. However, I would think an artificial break arising from these procedures would be relatively straight, rather than curved as in this specimen.
True enough. Just saying you have to be careful when purchasing any error(but you already know this) not so much when finding them yourself.
