Ruben Sierra #303 — frequently asked

Where do these Baseball card prices come from?

Prices are the PriceCharting price guide, refreshed weekly. Raw values reflect near-mint (NM) ungraded copies; graded values are per grading company and grade.

Is your baseball card centered well enough to grade?

Centering makes or breaks a PSA 10. Scan any card with Midpoint to measure its exact centering, get a grade estimate, and see what your copy is actually worth.
