Is this a lamination error, planchet flaw, or something else?

I took this 91P JFK out of a mint set. It is an average coin - nothing special, but the divet (for lack of a better word) between the 9s caught my eye. It is not a raised bump like a die error, but an actual depressed area on the coin. I should probably know what this is called, but am sure someone here will! The best I can think of is a lamination error (but doesn't look quite right for that) or a bad planchet. Thanks!



And here is a close-up:

Defective planchet or strike thru. Had a Lincoln same way, but part of the strike was visible in the "crater", so it was labeled "Defective planchet" by PCGS. Anything in the "crater", like part of the '9'??

I've seen a similar Morgan, but it was wierd b/c the crater should have eaten up part of a letter, but instead, it kinda molded around the letter... hard to explain...

Monstavet

No, the crater is completely sommoth inside. The 9 does not actually go into it.

Monstavet

Eh? "sommoth?" I mean smooth! The 9 stops right on the rim.

Wolf359

Ok, no design elements in the "crater". Any foreign material that you can see under a scope? If so, could be a strike-thru by an object stuck to the die. Note: You've about exhausted my knowledge here.

Monstavet

Nothing at all in there. Thanks for the input!

Looks like a classic struck-through error to me.

nwcs

Yep, strike through. And a pretty cool coin example.

Dog97

Yep. I'll third that it is a strike thru. Pretty neat. JFKs are tough to find with ANY errors.

Monstavet

Wow. This one was in my sell as quickly and cheaply as possible pile, but I thought it looked a little different. It is the first error coin of any type that I have found personally. Now, I don't know quite to do with it!

Trade you a clipped Roosie for it!

Monstavet

Naw. Not big into Roosies. But a trade seems a good way to go if I decide not to keep it. I may move it over to BS&T if I think it will find a better home.
