Has an uncanny similarity to the first Colony of Massachusetts shillings, sixpences and threepences.
Interesting that it has been struck near the edge like them.
The stamp reads P, retrograde N, E, D
This could be interpreted as Penny, New England, Denarius.
There were tokens in use at the Colony of Massachusetts contemporaneously on which both "penny" and/or "P" and/or "D" for "denarius" were displayed.
Another possibility is that the stamped cipher pertains to P for Samuel Paddy, and D for Jeremiah (Jeremie) Dummer, both silversmiths, apprenticed to the Colony of Massachusetts' mintmaster John Hull in 1659, and tasked with making coin dies for the Colony. The stamp is redolent of a silversmith maker's mark.
I have studied the Colony's coins extensively and the history around them and have been of the opinion that the production of a farthing, half penny and penny must have been considered and actioned, especially as there was a dire shortage of coinage, and especially so the low denominations.
Appears to be feasibly 17th century.
Diameter is 21mm.
Weight is 6.39g
The weight corresponds to that of penny tokens of that period.
Appears to be bronze, brass, or latten. (to be tested)
This was originally sold with early American coins as a hitherto unknown Mexican Hacienda token unlisted in Grove, Rulau, Ekland/Noe. That description was obviously a shot in the dark by the seller. It actually bears little resemblance whatsoever to any listed hacienda token.
