Select a print run and enter your card's serial number to see if it carries a premium. Add the player's jersey number for jersey match detection.
Understanding Numbered Card Premiums
Numbered cards (also called "serial numbered" or "/XX" cards) are limited to a specific print run — typically stamped on the card as "45/99" meaning card 45 of 99 total copies. While every copy is equally "rare" in terms of scarcity, certain serial numbers command significant premiums.
Jersey Number Match
The most premium serial. If Tom Brady is #12 and your card is 12/99, that's a jersey match — worth 2-5x a random serial depending on the player's star power and the print run.
Card #1
The "first off the line" carries prestige. #1 commands 2-3x over random serials. On ultra-low runs (/5, /10), #1 is especially prized.
Last Number
The final card in the run (/99 of /99, /25 of /25) gets a "bookend" premium of 1.5-2x. Paired with #1, they form a matched set.
Low Serials
Single-digit serials (/1-9) get 1.3-1.8x premiums. The lower the number, the higher the premium. This is pure psychology — low numbers "feel" rarer.
Frequently Asked Questions
What makes a numbered card serial number more valuable?
Three factors create serial number premiums: (1) Jersey number match — if the serial matches the player's jersey number (e.g., #24/99 for Kobe Bryant), collectors pay 2-5x more. (2) Low serials — #1 gets 2-3x premium, single digits get 1.5-2x. (3) Last number — the final card in the print run (/99 of /99) commands 1.5-2x premium. Random middle numbers have no premium.
How much extra is a jersey number match worth?
Jersey number matches typically add 2-5x the price of a random serial. The premium is highest on star players and lower print runs. A Luka Doncic #77/99 might sell for 4-5x a random serial, while a common player's jersey match might only add 1.5-2x. The market recognizes jersey matches as the most desirable serial numbers.
Is card #1 always the most valuable serial number?
Usually #1 is the second most valuable after a jersey number match (if one exists within the print run). Card #1 commands a 2-3x premium over random serials. However, if the player's jersey number falls within the print run, that serial almost always sells for more than #1. For example, on a Steph Curry /99, card #30 (his jersey number) usually outsells card #1.
Does the print run size affect serial number premiums?
Yes. Lower print runs amplify serial number premiums. A jersey match on a /10 card might command 5x+ because there are so few copies. On a /500 card, the same jersey match might only add 1.5-2x because there are many more alternatives. The scarcity of the print run multiplies the significance of each serial number.
What is a "1/1" and why is it different from numbered cards?
A 1/1 (one-of-one) is a card where only one copy exists — there is no serial number variability because it's the only card. 1/1 cards are the pinnacle of modern card collecting, often selling for 10-100x the price of the next lowest parallel. Since there's only one copy, every 1/1 is inherently a premium serial. This calculator focuses on print runs of 2 or more where serial numbers create varying values.
