hello everyone!!
would there possibly be anyone out there that would know about the 1901 9/9 quarter? it is listed on this site but there is no information on it other than the fact it allegedly exists, and i have also seen it listed on auction pages but i am unknowledgeable about what the difference is between the 9/9 and the standard 1901 - if so would anyone know where i could find information on it?

It's listed in Charlton's with a picture.
Not much premium for these as they are fairly common and there is little demand.

Thank you!! I’m just trying to understand what is out there and what I have, and I’m trying to organize my quarters into a album. I appreciate you taking the time to reply
