Brand new, and have been studying coins for about 6 months and would love some help, please!!!
I have 2 1976 D Bicentennial Quarters:
Coin A- Lettering on United States Of America , like on the I is thicker at top and narrows at the bottom!!!

Coin B- in regards to the lettering has an obvious difference, the lettering does not narrow, is thicker and more uniform top to bottom!!!

Not sure if you will be able to see the pics, but here we go!!!
