I thought that $20 would end up in your collection and it makes a very nice set, somehow all from the C plates.  Did you notice the difference in the fonts on the $20 as compared to the $5 and $10?  It has the new numbering font introduced in 1903, as expected given the Treasury Number starting with V.  I added a Quarryville, PA $20 Red Seal in PMG 15 to my collection.

I promised myself I would not get carried away with NBN. Stick to Federal currency. Ha! Just didn't happen. Putting sets together is a great hobby for me. How about those Arizona notes? The territorial notes seem to be off the charts with prices reaching that of decent automobiles for the red seal territorial from Nogales. Unbelievable how fickle that part of this hobby can be. Folks pay exorbitant money for utter rarity. I thought I would post an example of my other hobby. Finding interesting internationals at reasonable prices.
