Agree, possibly a clash die. A clashed die occurs when there is a malfunction in the planchet feeding mechanism and no planchet is fed into the striking chamber allowing the dies to strike each other. The obv. die will leave an impression in the rev. die and vice versa. Coins struck with these dies will exhibit details of both the obv and rev. on each side of the coin. The amount of detail can vary from barely discernable to very noticeable.
The one you show is not as strong but some people do collect them as is. Thanks for sharing.
