Interesting, although the “08” looks like it may have been altered. The “8” does not look symmetrical- if you notice the right side of it resembles the shape of the number”3” used on dates like 1913, 1923 and so on. Something wrong with the “0” as well, should be smaller and slightly higher.
I think it’s an altered date coin. A neat addition to a collection but not genuine in my opinion.
