What we have here looks like woodgrain at the molecular level, or at least baked into the piece's metallurgical composition.
This is a manorial token, not quite halfpenny size, issued by John Harvey of Dane Court, Tilmanstone, Kent, England, ca. 1720-1750.*
* No one catalogues these things in any detail, apparently, although I have stumbled across this one in a couple of numismatics tomes, like Batty (1877), but it's always strictly descriptive, without attribution. I'm assigning a confidence level of .85 to my attribution, based on my own research into all sorts of relevant primary sources: heraldry references, genealogical databases, land ownership records, etc., and don't forget the initials on the token itself
Please follow up with a reply if you have further clues, a reference work in which it appears, or the same token...or if you just like the wood look.
Thanks, everybody, and wash your hands!
