We all dream of going into a bank and scoring a box or bag of coins that has been sitting in their vault since 1964. But, of course that's not going to happen at any bank in the US. What about Cuba? There might be banks in Cuba that have US coins that have been sitting in storage since before the Cold War. Maybe $10 face value, or maybe $500. Who knows. I also don't know what might have been mandated by the Cuban government for any such coins or currency during the Cold War. Perhaps they were melted down to make Cuban coins, or melted and sold, or maybe they've been sitting in a bag or a box for 50+ years. I don't think there's enough chance of a big score to justify flying to Cuba, but if anyone is already planning to go there on vacation or business, it certainly might be worth checking out.
