I Know about the 2005 P Kansas quarter missing T in Trust but nothing on the 1999 P Connecticut. Do I have a rare one?
Grease filled die. Pretty common. Seems to be that for some reason, the "T" would get all gunked up pretty easily.
Greased filled die............oh. I see my amphibian friend has already given you the solution.........
That looks like a snake skin background......... Though not amphibian, it resembles reptilian.........
All State quarters and National Park are not well made and we are seeing lots of them deteriorating easily.
