Kurt P. writes: I have a 1792 gold 8 Escudo coin. The mint mark looks like an “S” with a circle on top it. The assayer initial’s, I believe are FM. The coin is in good condition. I was wondering if you know where this coin was minted and how much is worth.
The coin is a Spanish, Charles IIII 8 Escudos with the bust of Charles III (they didn’t know what the new king looked like so they kept the old portrait for a good number of years. (No e-mail and attachments back then). The Mint mark you described is Santiago, Chile, however the assayer would be “DA” not “FM”. Take another look at your coin. Values depending on condition: $1500 – $4000.
