Backed by silver lol 
Discussion
My dad gave me one of those as a kid an explained how money used to be backed by gold and silver. He grew up working as a goldsmith's apprentice in Greece as a kid.
He gave you a head start with that info. 🫡
That’s the head start my kiddo has. 🙏
I didn’t understand money at all until I found bitcoin. I’m glad my grandfather gave me these after I learned, having these tangibly validated that believing in bitcoin isn’t crazy
