Fuzzy Reverse Of A 71 Penny?

Probably cheating to agree with Mike Diamond, but well, I agree with Mike Diamond :)

Also, I would keep that guy. That's one of the more interesting error types you find.

The obverse has a sharp strike and the finned rim is a clue that there might have been something else in the coining chamber besides this planchet, similar finning(excess metal extruding between the die and collar) can also be seen on coins struck on overweight planchets. A die cap or split planchet in the coining chamber along with another normal planchet could create the same finning scenario.

Hello Mr. Biokemist, are you saying it's sort of a mystery?

sorry, but we really need clearer pictures, or maybe a scanned image

A capped die strike will sometimes leave either a brockage(incuse mirror image from the die cap acting as a die) or a ghost outline of the die design showing through a thinning cap. The intermediate stages usually show very little detail on the affected face. I suspect that Mike Diamond's hypothesis is correct and I would base that on the relative strength of the fuzzy reverse details.

A split planchet is basically a lamination on steroids, i.e. an entire face of a planchet splits off in a thin layer. In this case, the thin split planchet would have been in the coining chamber along with a normal planchet and the reverse of your coin was struck through the split planchet. In this scenario, there would also be a thin split planchet out in the wild somewhere with the fully struck reverse design.

I didn't see any quite like this on ebay, is this have good value in your opinion? Any comments are appreciated.

sweet, but I'm holding on to it. I think it's pretty cool
