My vote is for struck counterfeit..
It wouldn't be a Henning. Those were minted to be passed off as face value around the same time period as the original mintage. Struck counterfeits were minted decades later, not to be passed as face, but to fool collectors.
A mold is created with a genuine coin. The coin looks like it's About Uncirculated with Fine details (from the host coin). The wear is coming from the host coin, not the coin you have.
I don't have the coin in front of me, but from what I can see I would say counterfeit.. sorry
