Your Opinions Please... Error or Damage?

[ndgoflo]

Hi all, I was just taking a look at some pocket change and I came across this Connecticut quarter (P mint).  It doesn't appear to be post mint damage to me, but what do I know? At first, I thought the die was "crumbling" around the perimeter, but wouldn't that be raised on the coin instead of incuse? Any insight is greatly appreciated.

Interesting item. I'm curious to know its cause as well.

I have this same topic posted on the PCGS board as well. The few replies that I have gotten all think it is a "collar clash". I don't know exactly what that is, but I'm willing to learn.

Collar Clash

Occasionally, the die shifts slightly out of position and, instead of fully striking the planchet, it partially strikes the collar. As with a die clash, the design of the collar, whether smooth or reeded, is transferred to the die. This, in turn, is transferred to the coins struck by the die. Most often, only the reeded collar clashed coins are of collector interest, but again, only if there is significant design transfer.

Google.com is a wonderful tool for learning.   

I'm not sure if that's a collar clash or not, but I'm definitely no expert on error coins, not even close.
