so I just started collecting bank notes (have almost 200$ face value in UNC-Gem varying from 1$ - 20$
I'm really confused with the "Printer" categories in Charlton.
example: I have a 1979 20$ bill (Thiessen/Crow)in CH UNC (51 serial number). in Charlton theres 4 different Category Numbers. BC-54c, BC-54cA, BC-54c-i, BC-54cA-i
I'm so confused as to how to tell how to price it (the value ect)
