Well, I wish my mom had let me keep it. She took it and gave be a dollar bill. I didn’t even know better till I was older, and it was too late then.
I remember asking her when I was kindergarten age why they had those, and she said they had some put away in case the currency became worthless- I was clueless, but shut up-Mom didn’t like to answer questions.
I had built up a pretty nice collection of silver coins, until one day my mom needed a tank of butane (back in the day before propane), and there went my collection of silver coins.
My grandma, who was one of the most righteous people I've ever known, btw, there's a huge difference between "religious people" and righteous people, prophesied that one day I'd have plenty of gold and silver, and she was right! But what's plenty for me, probably ain't for some. ;)
