How much is a 2006 $100 Silver Franklin Proof worth?

It's a 'private mint' issue, put out by the Washington Mint. It's a replica $100 bill, meaning that it holds very little interest for coin collectors. These private mint issues are hyped toward those who think that if they buy something 'limited edition', it will be worth a lot of money someday. Once in a great while, that does happen, but most of the time you can't get anywhere near what these things originally cost. Notable exceptions are Franklin Mint silver items from the early 1970s, when a single silver 'coin' had less than $2 worth of silver and were sold for $10-$12 each. Today, their silver value has exceeded the original cost, but after accounting for inflation, still turned out to be a lousy investment.

The current value of the silver in one of these Franklins is $64, at a spot market price of $16. One of them sold recently on eBay for $90 including shipping, which is a pretty good percentage over bullion value, but probably less than what the original sale price was. I don't know what that was, but I'm guessing that it was at least $100.

What's the purity? If it is .999 pure Ag, then it's about $62 worth of silver. Most coin shops dont deal with those non-US Mint commemoratives, so it might be hard to find a buyer for it.

about $65

That made no sense, what wAs the question?
