This seller has a whole bunch of 2000 Finest Gold Refractors listed and multiples of some big names. Upon closer inspection the ones he has listed don't have the jagged/saw-like/die-cut border they're supposed to have (example below):
Are the ones he has listed backdoored versions? I messaged the seller and he said they came in a collection he purchased.
He also has a crapload of unnumbered 2000 Stadium Club Chrome First Day Issue cards. These are supposed to be numbered /100 but the ones he has are missing the serial number. And those aren't the only 'missing serial number' cards he has listed.
