1963 20 Dollar Bill, 1950 D Ten And Five, Need Help With Grading And Mintage And Plate Rarity,

The 1963 $20 was one of 4,480,000 printed.
The 1950D $10 was one of 33,840,000 printed.
The 1950D $5 was one of 25,200,000 printed.
The above numbers are notes PRINTED, not minted. Coins are minted and our paper money is from the Bureau of Engraving and Printing.

I don't see anything significant about the front or back plate numbers on any of the notes. It's almost impossible to grade them from partial images.

Sorry - it is D4 and D2 - but still the same question. Notes are not my area so I am trying to learn here. Thanks

The upper left is the Plate Position and the lower right is the Plate Number.

The plate position tells you where the note was on the sheet, before being cut. The plate number is a reference for the BEP to track how often the plate has been used.

And we need to see photos of the entire note to offer any sense of a grade. Impossible to do so with these partial note images.
