Not everyone thinks of revaluing silver proof sets when silver goes up like they reprice bullion coins. I have seen F barbers priced less than melt when silver spikes and no one remembers to look at collectible coins and reprice them due to silver value. It happens.
With the virus and nasty winter weather cutting into peoples' livelihoods, I'm sure Pawn Shops are seeing a lot of business with people unloading junk silver and "Oh, these were my grandpa's old coins, what can I get?"
