I think it's safe to say it's at least a double strike. There appears to be at least three lines of
legend running vertically from the bottom of the
reverse. This seems to indicate that the
planchet was rotated 90 degrees between strikes.
As oriented in the picture......The top line appears to show a "U", then a double "SS", and a double "II". Forward or backward, neither makes sense. And the letters are clear enough that I don't think it's due to a double strike. It's tough to figure out how any of that could be read as IHSUS.
The second line from the top appears to be (X)RISTUS, but retrograde. Likewise, there's no obvious distortion to indicate a double strike when the
planchet was in this orientation.
The line of
legend across the middle is a real mess.
I can't see any clear signs of multiple strikes on the
obverse, such as a second outline of the
nimbus.
Interesting coin, all around, though!
