yep I know about Gresham's Law.
Good money chases out bad, It means you're going to save your silver coins and spend the inherently useless paper.
An interesting update: I was at a swapmeet and got 3 sterling silver spoons for $16. Cool, I thought! I looked up the melt value and got $66! I tried hustling 'em to the antique stores locally, thinking maybe I'll be a nice guy and settle for a round $50, well, I got $30. The thing is, stuff like spoons, you just don't know for sure if they're for real, one lady at one store thought two of them were plated. And they all told me, they sell for less than melt value. I've learned that the silver buyers who just buy for metal value, pay about half of melt. I sold them because there were things I needed to buy, and I want my long term savings to be in coins not spoons and stuff like that.
