Is it worth grading?
The prices above are for raw, ungraded copies. Grading only pays when the graded copy clears the raw price plus the cost of grading it, and on cheaper cards it usually does not. Our comic grading cost calculator works out the break-even for any value you type in, including shipping both ways and seller fees.

How we collect these prices
We query the TCGplayer market price for every card on this page once a day and append it to a price history we maintain ourselves. The series began on 2026-08-13 and now covers 44 days. “Market price” is the level actual completed sales cluster around, not a seller asking price. Figures are for raw, ungraded copies. When a source is unreachable we record no value for that day rather than carrying the previous one forward, so a flat line means a flat market, not a gap in collection.
