A Nomad OS Study of Raw, PSA 9, and PSA 10 Card Prices
A year of CardHedge-reported sales across thirty selected player markets. Nomad OS measured changes in Raw, PSA 9 and PSA 10 prices and the dollar gaps between them; the study explores how those patterns differed across players, alongside grading and sporting events.
Methods and evidence
