A baseball card is worth the median of recent completed sales for the exact same year, set, parallel, grade, and condition. Do not average raw card comps with graded card comps. On release weeks (Topps Series 1, Bowman Chrome) comps move daily, so weight the last 7 to 14 days. MaxBid AI scans a baseball card from a photo and returns a comp-backed max bid in under 10 seconds.
On Topps Series 1 release weeks, MaxBid AI baseball card scans pull a median of 9 to 12 sold comps from the last 7 days alone.
Your baseball card is worth the median of recent sold comps for the exact same year, set, parallel, and grade. Match condition tier exactly. Vintage cards weight condition more heavily. Modern cards weight parallel and grade.
Condition and authenticity dominate vintage baseball card value. A 1950s rookie can swing 10x in price between Good and Near Mint condition. Always grade comps must come from the same condition tier as the card in your hand.
Usually one of three reasons: mixing parallels (base vs numbered), mixing raw vs graded comps, or including comps from outside the last 60 days. Filter harder. On release weeks, narrow further to the last 14 days.
Not automatically. 1986 to 1994 baseball cards are the junk wax era, printed in such high quantities most have no resale value above $1. Vintage cards pre-1980 in clean condition can be valuable. Always check sold comps for the exact card.
