Selling Guide

Where to Sell

eBay is the best platform for this specific card due to the high volume of Exhibit collectors. For a higher-grade specimen, a specialized sports auction house like Robert Edward Auctions would be appropriate.

Selling Tips

Do not grade this card unless you believe it will hit a PSA 5 or higher, as the grading fees will outweigh the value added for low-grade vintage. Use 'Exhibit Card' and 'HOF' in the title. Ship in a dedicated oversized top loader to prevent bending.
