That two dollar bill is an old silver certificate and has numismatic value. LOL
Actually, that’s a bearer note, not a silver certificate. Says “will pay to the bearer on demand two dollars”. A “dollar” is actually a very specific term, that is not what people think it is.
Originally, we had gold/silver certificates that promised to pay to the bearer X dollars of gold/silver on demand. The “dollar” they were talking about was actually a certain weight of gold/silver as specified by congress. (Through the power to regulate the value of money).
Later the verbiage changed to “will pay to the bearer on demand, X dollars”, without specifying gold or silver payment.
Now, it’s just a promissory note that promises to pay you nothing.
