Why Bulk Sort & Select?
Bulk Sort & Select - Important Submission Guidelines
To help ensure the best experience and clear expectations before sending your cards, please review the following:
- ●Please note: Sports cards from 1985–1996 historically have a lower percentage of qualifying for GCC grading, due to common manufacturing and condition challenges from that era.
- ●Cards not selected for a GCC Sticker are charged 25% of the applicable tier price. If fewer than 15% qualify, the minimum processing charge is capped at $75 for top bulk tiers and $50 for lower submission levels. This service still includes a professional review, value identification, and your cards will be organized and securely packaged upon return.
- ●A 100-card minimum submission is required to qualify for this service tier. Cards may be submitted in boxes, binders, and/or holders.
- ●To help offset shipping costs, larger submissions qualify for a shipping credit:
100+ cards → $10 shipping credit
250+ cards → $25 shipping credit
Our goal is to provide valuable market insight, reduce uncertainty, and help identify the cards most worth grading—while keeping the process transparent, efficient, and worthwhile for every collector. Thank you for trusting GCC Grading.
