My first thought was that this was an uncentered broadstruck. At a closer look it looks like at least two sets of design elements close to the rim. Not one as from one strike. It also looks like it has a clip, but it's only half way through, so it could be damage. Is it struck more than once? If not, what is it? Opinions?
Looking closer at the rim it looks like it has been struck 3 or 4 times... Shouldn't that be visible in more places? Any thoughts?
