Ok, so please do not laugh, because I am still learning the in's and out's of pre war stuff.
So I was watching You Tube videos of T Cards and saw on one video featuring backs that had info on "overprints".
This is something I had never known about.
So I went down to the card room, looked at my T-Cards and I am so happy to announce that I DO have a factory #649 Overprint!!!!!
I am so happy!!!!
So how rare are they, and how much % more valuable are they then non overprints?
Thanks guys!
