1 of 1 Cards: Here's Everything You Need To Know
Key Takeaways
- A 1/1 card has a production run of one, meaning it’s guaranteed to be the only card of its kind to ever exist.
- 1/1 cards aren’t the same as Pop 1 cards, which are cards that get their one-of-a-kind status from other factors, such as PSA grade, misprints, or ownership history.
1 of 1, or 1/1, signifies that a sports card is the only one of its kind in existence. Unsurprisingly, 1 of 1 baseball cards, football cards, basketball cards, and other sports cards are extremely coveted by collectors, as they represent the pinnacle of rarity and exclusivity.

Frequently Asked Questions
How rare is a 1/1 card?
A 1/1 card is the rarest possible card because only one will ever be produced, meaning you own a true one-of-a-kind card.
How do you value a 1/1 card?
There are many factors that determine the value of a 1/1 card, including its market demand, ownership history, condition, grade, brand, set, and featured player.
Should 1/1 cards be graded?
Getting 1/1 cards graded is a gamble. If the PSA (Professional Sports Authenticator) assigns a perfect grade, the card’s value could increase. However, a less-than-perfect grade could decrease its value.
Most experts recommend only getting 1 of 1 cards graded if you’re sure it’ll receive a PSA 10 (Gem-Mint) grade.

Are 1/1 cards worth the risk?
Flipping sports cards for profit can be lucrative, but profit isn’t guaranteed. It’s important to thoroughly research your investment and perform a risk assessment on a card-by-card basis.
What is the most expensive 1/1 card?
The 2007-08 Upper Deck Exquisite Collection Dual Logoman Autographs Michael Jordan & Kobe Bryant card sold for $12,932,000 in August 2025, making it the most valuable sports card of all time, as of 2025.
1 of 1 vs. Population 1

It’s important to understand the difference between 1 of 1 cards and Population 1 (Pop 1) cards.
- 1 of 1: From the first second the card is printed, it’s guaranteed to be the only one of its kind that will ever exist.
- Pop 1: Pop 1 cards weren’t originally produced as 1/1s, but they’re one-of-a-kind cards due to other factors like grade, misprints, or ownership history.
1/1 Example:
Let’s say we have a Topps Transcendent Cut Babe Ruth 1 of 1 baseball card, which features a real Babe Ruth autograph sourced from a historical document. Before it was even printed, it was intentionally designed to be a 1 of 1 card. Reproducing that original signature is impossible.
Pop 1 Example:
There are around 50-60 known 1909 Honus Wagner T206 cards, but the “Gretzky” Wagner is the only one with a PSA 8 grade, as well as the only one once owned by hockey legend Wayne Gretzky. It’s technically a 1/1, but only because of its grade and ownership history.
How to Identify 1/1s

1/1s can take many different forms, so the first step is to get familiar with the specific sports card manufacturer and product line.
For example, let’s say you’re ripping packs from a Panini National Treasures football hobby box, hoping to find 1 of 1 football cards. Here are some of the 1/1s to watch for:
- NFL Shield 1 of 1 cards have an NFL logo patch made from the player’s game-used jersey.
- Rookie Patch Autograph (RPA) Platinum cards have a patch accompanied by a signature.
- Laundry Tag cards feature tags from game-worn jerseys.
- Printing Plate cards feature the actual plate used to print the card.
Besides these types of product-specific attributes, a 1/1 card will usually have “1/1” stamped on it.
