If you plan to print counterfeit $500 bills, you may as well print the $1,000, $5,000, or $10,000 bill (good old Salmon P. Chase). They were all discontinued in 1969.
Ya, that’s what I thought, that all bills over $100 were discontinued years ago.
What would a counterfeiter do with $500s or $1000s?? I mean, if you try to do money laundering or just try to deposit them in a bank, such bills will be studied very carefully, precisely because they aren’t in circulation anymore.
