Probably had grease of something filling the T http://www.error-ref.com/struck-through-smooth-viscous-material-grease-oil/
Yes, it's just I have heard a lot about these quarters and I am happy I found one. It's the thrill of finding errors I like.
Regardless, it's a good addition to your error collection, Sheila. You will find that some people try to sell these for more than they should by giving it an unusual name...........atheist coin. Chris
You miss the point. This is cooler than had a different letter been filled. Grease fillers are common. This particular one is cool.
I've got a bicentennial "In God We Rust" quarter from circulation. It wasone of the first 1976 quarters I found back in the summer of 1975 when they came out. This one is from a clipped planchet.
