I don't think it was a mis-date. From what I understand Reggie was churning winged eagles out at a good rate during this time frame but wasn't selling them. so he probably did make the belt in 2003, but when it sold they filled the certificate out as the date of sale and release into the world, which for this was 2005.
not every WWF logod reggie parks belt has a serial number on it. I know because I have one. I have a WWF reggie winged eagle made in 92 so it was before any licensing agreement. so i might have one of the few WWF reggie winged eagles around with no serial number.
1:07 Did anyone else ever notice that the globe on the right side of the banner is just a mirror image of the western hemisphere? That's the Americas on the right and Europe/Asia/Africa on the left (it's backwards). The globe on the left side is normal
