Nice! The 1878-P looks great. The 1888-O could have possibly been cleaned long ago and retoned with that unusual patina. . The 1921-O, well, that scratch... Hope you got them for a decent price considering the damage.
That's a 1921-D. The New Orleans Mint ceased production in 1909. Do you have images of the reverses? Yep, the 1921-D would likely get "MS Details - Damaged". Chris
1878; Nice, original-looking surface. VF25 1888; Don't know what to make of that color, looks like it was smoked. So I'll say VF30 details. 1921; That scratch is a killer. MS62 details.
Sorry, I understand that. It was a mistype. I just took a quick scroll up when typing my previous message and it caught my eye as an "O" even though I know that is IMPOSSIBLE! Unless there was a sudden Comstock Lode de-ja-vu moment and they opened a brand new mint in New Orleans over ALL OVER AGAIN! hahaha.
Thanks for the opinions! I actually didn't pay for any of these. Two were either from my mother or grandmother and the 1921 was found in a large box of wheat pennies someone gave me.
