Sorry to tell you, they are copies. They run about $2-$5 on eBay. If they were genuine, a few thousand dollars. Nice to have as examples, but they sould be marked "COPY" to keep them legal. Sorry if this is bad news. Welcome to the Forum!
They were probably made in China and is why "COPY" is not stamped on the coins. All of them look questionable. It's best to avoid buying raw coins like these, especially on eBay, unless you are very familiar with each series. Chris
