That said, it could also be illegal to buy counterfeit currency, even if you don’t intend to sell it.
Do you have a source for this? I've never heard of it but would be really interested in looking at, say, a disassembly of applicable firmware.

"Crimes Involving the Use of Counterfeit Currency The use of counterfeit currency can violate both federal and state law.
Under federal law, the use or attempted use of counterfeit currency is illegal if the person has the intent to defraud the recipient. A conviction for the offense carries up to 20 years in prison and a fine. A conviction for producing counterfeit currency similarly carries a maximum sentence of 20 years imprisonment and a fine, as does a conviction for merely possessing counterfeit currency. All of these crimes require that the prosecutor prove that the defendant acted with the intent to defraud."
"intent to defraud." being key here...
I currently have some counterfeit boullion and fake Magic the Gathering cards. I find the idea of effectively-worthless items that appear very valuable to be quite aesthetically appealing. Fake art seems cool, and I've been looking into movie prop money.
"Real" counterfeits would be an interesting collection item, but would probably deface the back/front of each bill with word "FAKE - do not spend or accept" so I could display them, but reasonably say I did not intend to spend them.
