Some time ago while discussing an 1804 dated contemporary 1 real
http://goccf.com/t/276447&) realeswatcher briefly noted having seen similar examples dated 1782 and bearing the Mo mint mark. Today I acquired what I believe to be one of these. Although the mint mark is not visible, the date is. The coin is "white metal" rather than silver, feels underweight (though I have not had the chance to weigh it yet) and has a plain edge.
I'd appreciate any insight from realeswatcher and others :)
Thanks!
