How Is This Broadstruck Coin Possible?

I would like to see pictures of the whole coin, both sides.

This one looks like it involved another planchet during the strike.

I am sure that if Mike D. pops in he'll be able to explain it without seeing the whole coin. On really whacky errors like this, I like to see everything:-)

Thanks,
Bill

FIR is correct- two planchets would be involved here. The one shown was a 40-50% clip(probably ragged or straight, not curved) and it overlapped another planchet which created an indent strike on the reverse with about 10% design showing. Indent strikes create a uniface surface with no design on the area of planchet overlap.

The other coin, assuming it was a complete planchet, would have about 40-50% obverse with the remainder a uniface indent strike and the reverse would be 90% complete with a 10% indent strike. Obviously, this all takes place outside of the collar so both coins would be broadstruck as well.

When you have a matching pair, the value is sky high because it would be quite rare to have both of them but sometimes you can get lucky in a bag and find both pieces or they may even be bonded together. The percentages may vary a bit and it is even possible for there to not be 100% of a strike between the two coins due to incomplete overlap. The area of the obverse where STATES would be is probably not present on either coin.

Ok, I think I covered all the bases there and hopefully everything is correct, my brain now hurts from too much thinking and spatial orientation processing...

The slab is accurate and is what I would have said after seeing the entire obverse and reverse of the coin.. Also, Biokemist's post explains it beautifully.

It was an incomplete planchet (clip), that was struck with another planchet between the resulting coin and the obverse die (indent) and due to the nature of the strike and it being outside of a collar, it is a broadstrike.

The (clip) occurred before the strike. So somehow, the incomplete planchet and another planchet were fed through the coining chamber simultaneously.

Whether it exists anymore is questionable as it may never have left the mint, theoretically, there would be a piece out there that would fit in the general shape of the indent that has the rest of the obverse of the quarter struck on it.

It's a nice error. Mike D. might , if he sees this also add more detail. I noted the general concept and Bio, nailed it down!.

Have Fun,
Bill

Amazing!
