The density at 9.5 is a clear indication of a counterfeit host. Provided the test is accurate you have the answer. The dies seem to be genuine B of E types at least to my eye. The use of a Circulating Counterfeit as a host coin for one of the Bank tokens is not unheard of. I take it that Heritage
does not indicate the host is not genuine.
I really like the coin. I would expect the coin is scarcer than a genuine issue.
