William Contreras's key rookie cards, by our criteria
- First licensed base RC: The licensed base rookie card from the earliest year in the player's checklist. Where an Upper Deck Young Guns card exists, that card.
- First chromium RC: The licensed chromium (Chrome, Prizm, Optic and the like) rookie card from the earliest year in the player's checklist.
- Scarcest licensed RC autograph: Among licensed rookie-card autographs in the player's checklist, the one with the lowest stated print run.
- First prospect card: For a player whose rookie cards are not out yet, or a baseball player's Bowman 1st: the earliest prospect card in the player's checklist. Not a rookie card.
Which William Contreras card is the real rookie card
Topps has held the exclusive MLB license since its 2009 deal, so his licensed rookie cards are all Topps products. Contreras debuted with Atlanta on July 24, 2020, and his RC logo cards came in 2021: Topps #390, Topps Chrome #51, the Topps Chrome Rookie Autographs card RA-WC, Bowman Chrome #38 and a shared Topps Heritage rookie card with Tyler Stephenson (#81). He signed with the Braves as an international free agent in 2015. Do not confuse his cards with those of his older brother Willson Contreras.

Grading William Contreras cards
A PSA 10 (Gem Mint) or BGS 9.5 is the top grade most collectors look for; it means sharp corners, clean edges, centered printing and an unmarked surface. A graded card and a raw one are different cards to look up.
How PSA, CGC and Beckett grade
PSA
- Top grades:
- Gem Mint 10, then Mint 9 and NM-MT 8.

One overall grade on the label. Centering weighs heavily in it.

- Pristine 10 (virtually flawless, 50/50 centering), then Gem Mint 10 and Mint+ 9.5.
- Half grades:
- Yes, from Fair 1.5 up to Mint+ 9.5.
Authentic (AU) for a genuine card that cannot take a number; Authentic Altered (AA) for one that was altered.

How to identify your William Contreras card and check what it sold for
- Find the year and maker on the back of your William Contreras card, and the card number, usually top or bottom on the back.
- Check the front and back for a serial number (for example 23/99) and for a colored or patterned finish: those mark a parallel, which is a different card from the base version.
- Look for the RC logo or the word Rookie. A card from before the first pro season, such as a Bowman 1st or a college card, is a prospect card, not a rookie card.
- Note any grade on the slab label (PSA, BGS, SGC, CGC). A raw card and a graded one are different listings.
- Search sold listings for that exact year, set, number, parallel and grade. What a card sold for is a better guide than any asking price.
Check William Contreras rookie cards in eBay's sold listings or eBay's price guide for that exact card.
