Went into a coin shop in Almeria yesterday for a look round. Rarely do they have American coinage, but there was some Nickels,Dimes and Quarters in a box on the counter, 32 in total and he was happy to take 5 Euros for them. One Dime was 1962 and another 1964, so silver. Disappointment hit hard when he told me a customer bought all the dollars and halves the day before. everything was from a small collection he had done a deal on. He now has my phone and e-mail for the future. Of the rest there were two with a bit of interest as I like coins with anomalies. 1st has prominent die polishing on the reverse and the 2nd is an obverse MAD
Die polish marks? Looks like some angry employee grabbed a stiff wire brush and went nuts on it. Good luck on this new lead for possible coins.
