I've picked up a few different Masonic mark pennies over the years, but none as curious as this one. The design on the obverse is somewhat like the bust on old Corsican coins, and I haven't seen one with the denarius denomination (if indeed that;s what it is) before. The mark on the keystone resembles the Chinese 5, but I don't think that's what it is. I believe that the Occident chapter is in Canada. I know that Masons don't like to talk about these things, but I do think that this one has a neat design.
