I remember having read (as an example of the fact that use of coins, and therefore their loss, may largely postdate their emission—unfortunately, I cannot remember the source of this mention) that Roman coins were still used in North Africa at the time of French colonisation (probably as bullion). I would be interested in any sourced mention of such a late use of Antique coins—not only Roman coins in Africa, but pretty much any instance of an Antique coins being used far into medieval or modern times. Thanks!
/e the phrasing of both the title and the message imply a written source, but an archaeological example, such as the presence of a coin in a demonstrably late context, would also interest me.
Not for the purposes of circulation, but I came across this one entry in JSTOR that I thought was an interesting use of antique coins into the medieval era.
"...at Anemurium in southern Turkey a pierced bronze coin of the second-century emperor Marcus Aurelius was found on the floor of a house that was abandoned in the second half of the seventh century."
I might do some more digging as this question intrigues me as well.
