That's great information Darin and I really appreciate it thank you very much. I was thinking the date stamping on the corners had more to do with it. Turns out it's the actual corners themselves.
A lot of great info on this form on fakes and it's really great having awesome resources like you to reach out to. I've been reading through all the ones on here that have been identified and have learned a lot. It's amazing how people will drop a couple hundred bucks on a sign on Ebay without even knowing what they're buying. I'd like to think they were just too trusting but would have to believe they're just naive. but also pretty sad how many are trying to pass something off as something it's not.
Thanks again and take care.
