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.
