I have a 1871H quarter which is between a 40 and 50 grade. I am very confused by the difference in obverse 1 & 2. What do I look for?/ When I click on both it shows the reverse with the "H" but both appear identical to me. Can anyone provide a clear detail, thanks.

On an Obv 1, the right end ribbon is off center to the RIGHT. On an Obv 2, the right ribbon end is off-center to the LEFT.
