Neat find on the Balboa, the Panamanian currency is still pegged to the dollar, and I believe most of their coins are still minted here, I know I have a bunch of cents, nickels, dimes, quarters and halves, and they are all identical in composition to our coins. I really like the old silver Balboas, I have a half a roll of BU Balboas from 1966, each one contains 26.73g of 0.900 fine silver, just like a Morgan or Peace dollar!
