Whenever my grandmother visits, she gives me whatever interesting coins she’s acquired on her travels around the world. Most of them are regular circulation coins, but there’s one that I can’t identify. I can’t tell if it’s extremely worn down or if it’s so old that it predates minting. That one side seems to be struck off-center seems to indicate that it is indeed hand-struck. The obverse seems to have some sort of writing that may be Middle-Eastern (it doesn’t look particularly Indic). The reverse shows two figures in hats (to my mind, I see a couple of sherpas confronted by a snake—although their hats strike me more as Peruvian). Does anybody know anything about this coin?
