dabateman Posted July 19, 2019 Share Posted July 19, 2019 I washoping you found a filter for $20.You can see most of the security features. In UV it would high light the others. There are also suttle difference between series. Here you have the 2013 one. Rare notes have a star at the end of the serial number, instead of a letter. That is when a mistake was made and it was pulled. Link to comment
Andrea B. Posted July 23, 2019 Share Posted July 23, 2019 That light banding on the left in the SWIR of the back of the $20 is weird. Link to comment
