Hi, These two I recently bought here in Brazil, very low price, and great looking coins. The photo manipulation is restricted to enhance details to facilitate your assesment. Thank you.
The 1880-O looks AU and possibly cleaned (the fields look clear compared to the areas around the devices which show toning and aging). The 1922-P looks AU/BU with lots of scratches and graffiti.
One more comment that shadow under liberty's eye and on the cheek (1st coin) is glue of a paper sticker that was attached to the coin and I carefully removed. I wont clean it because i dont know how to do it without ruin the coin.
The 1880-O looks AU-55 maybe 58 but I'm sure it's been cleaned at some point in the past. The 1922 IS scratched and easy to find. It would go for junk value I think. Glad you didn't pay a lot for them.
If you had to clean it, the best bet is a q-tip dipped in acetone. Drop the acetone on the affected area and let it set for a minute and see if it gently wipes off. Once done, rinse the coin in cold water. I don't recommend cleaning - but I have removed junk this way in the past from circulated coins.
