Are these two notes genuine errors? Very unusual as regards to errors!

[Palm Island Coins-migratio]

Hello, I manage a coin shop in Florida and received the opportunity to purchase a decent and higher end paper error collection which I tend to specialize in. These two I have never seen or heard of before.

-The 1990 $20 has the district number and seal in the same color green ink as the serial numbers and treasury seal. VF with tattered edges and a obverse teller stamp.

-The 1957 $1 is a partial back to front offset on the right of the obverse but also has an additional partial B2F offset on the left that is inverted, at an angle, and also not a mirrored image. Could this be an offset of an offset? AU with no problems

I inspected both with magnification and saw no signs of either being tampered with. Any advice and value would be appreciated. Thank you!
