Ok just went thru my 1925 and 1926 cards, first its really hard to tell the difference just by looking at them but as soon as I scanned a few side by side it became a lot easier, here you go, what do you all think-
First here is a 1926 from the lot I got (that had like 11 1926 and 3 1925's) and a 1925 just so we can compare cards that we know are 1926 and 1925's -
Second here is a pick of a 1925 in the lot I mentioned above as well as another 1925 I picked up a few years ago-
Here is a 1925 that clearly has a blue tint, here is a 1925 only player Brooks-
I only found a few that for sure had a blue tint, my ruth did not, I would guess maybe 25% or less had the blue tint.
