1998 Skybox Precious Metal Gem - Brett Favre /50
 

Good afternoon,

Please see attached Brett Favre PMG #4 Card Back; on the rear, it doesn't show a serial number down in the lower right corner where it's notated /50PMG. Does anyone know why the card may be like this? I've attempted to locate some information on the internet, but keep running into dead ends. I've seen various different PMG cards, but nothing like this. Any help would be greatly appreciated, thank you...
