Hello, I was just going through an old stamp collection my mom gave me. She inherited
it from a woman in Colorado Springs born in 1906. I found this 2c Washington and from comparing to photos on the internet I couldn't tell if it was a 634 or a 634A. I understand that there is a type 1 and type 2. Sorry for my ignorance, I collect coins, not stamps. So my knowledge is below basic.
Anyway, thanks for any and all input. Cheers!
