This is a one of a kind. At least no one has found another. On the surface, it looks like a fairly common Super Tournament. But look closely at the logo. Supers always say either "Tournament" or "Tournament Return" right above "Tops" on the logo. Not on this one.
No one is sure what the story is on this. It could be an early prototype. It is unlikely a mis-stamp, as at least part of those words should show. It's also been suggested this could be stamped from a broken die, and that part of the logo was machined down, when it became damaged.
In any case, this is a mystery, and a very rare yo-yo.
