Detector pens use iodine to detect ordinary paper and did not react with these bills. However, rubbing alcohol will smear the ink to detect fakes. Also the bills lack a security strip and watermarks. https://cowboystatedaily.com/2026/0...to-riverton/ Inordinately fascinated by bits of metal with strange markings and figures Report this Post to the Staff

Sap Moderator Australia 16816 Posts	Posted 06/08/2026 9:19 pm I think "bleaching off a low-denomination note and printing a higher denomination on the blanked banknote" has been a counterfeiting technique to foil the detector pen for a while now. Making it harder to do this was the main reason why the different denominations are made more distinctive in terms of background inks and physical differences such as different security threads for each denomination. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff

I believe that was the purpose of the "security strip" placed in different positions on the bill along with the denomination printed on the strip beginning in 1990. I used to pull them out with a tweezers when I was younger. Report this Post to the Staff
