jersey numbered doesnt add value to the card, its just adds worth because people are willing to pay more because its a jersey numbered card. you can make up so many ideas with numbering, i personally look for cards numbered 6 because its the amount of championship rings, it doesnt make it a 1/1 and neither do 1st and last numbered cards make them 1/1's...a card numbered 789/999 is a 1/1 because its the only one numbered 789...also just because the card has 1/50 and 50/50, it doesnt mean that was the first card made or last card made, its just the first card that goes through the stamping press which for me isnt always a good thing because they could f*ck it up.
