How to identify your Mason Miller card and check what it sold for
- Find the year and maker on the back of your Mason Miller 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.
