It is quite possible. Counterfeit detection pens are generally inaccurate at best and can mark some older genuine bills as counterfeit and counterfeit bills as genuine, and as such should only be used if there is a lot of question about the bill's authenticity.

Banks were in addition required to hold any bills that were brought in and redeem them to the Treasury, but there was no wholesale withdrawal and they were never demonetized.
