[More of my family's misadventures with silver.]
It turns out that my great grandfather had saved a small chest full of those silver coins and it had been passed down to his son (my grandfather) who then didn't get around to officially giving it to anyone and almost everyone forgot about them. His daughter (my aunt) somehow got possession of them. By the 1970's these coins had been sitting locked up for about a century when my aunt came across them when she was moving some boxes around.
She had recently been over to dinner at one of her friend's house and was very impressed with their beautiful silverware. She coveted them but couldn't imagine being able to afford such a nice set of her own. That's when she came up with her scheme. She took the box of useless old silver coins and brought them to a silversmith. They made a deal in which she gave the coins to him and a pretty good sum of money to melt the coins down and turn them into a set of flatware.
My Father shakes his head when he tells the story convinced that the silversmith would have been far too shrewd to melt those antique coins. He probably kept them for himself and acquired a set of flatware to give to my aunt, telling her that it was made out of the coins that she gave him. I don't know what a set of 1970's silverware is worth today but I'm guessing a lot less than a chest full of rare Ottoman coins.
Here is another silver scam.
