I won't say which quarter this is right now, but started going through a Loomis box this afternoon and came across these two out of separate rolls. Still have a lot left to check. These pics were taken with the Dino-Lite microscope light as it was dark outside and I had the lens pretty close. It really shows up with a loop under an Ott-Lite also. This is two different quarters. At different angles you can see it stronger. Zooming out some on the quarters it is more evident and I have not marked every single spot. This is pretty dramatic in my eyes, especially the P mint mark. So let me hear it!!
@keemao All of the striations extending from the center of the coin outward to the rim are indicative of die deterioration. Chris
