GMA and Bargain Graders
Bargain graders (GMA, KSA, ISA) command 0.2-0.4× PSA at the same numerical grade. Recognize the holders and price accordingly.
Why discount applies
- Inconsistent grading standards across submissions
- Holders historically rejected at major auction houses
- Sub-grade calibration loose vs PSA
- Collector perception: 'graded by GMA' = 'wouldn't get a clean PSA'
When you see GMA in comps
Adjust: GMA 10 → assume PSA 8.5 equivalent. GMA 9 → PSA 7-8. Use this when sniping eBay listings — GMA-slabbed cards may be undervalued IF the underlying card is clean enough for PSA cross.
Cross-grading EV
GMA 10 crack → PSA: typical outcome PSA 8 (60%), 9 (25%), 10 (10%), damage (5%). EV positive on cards where PSA 10 > 3× GMA 10. Run the math before cracking.
Where this fits in the X3 empire
Used in eBay sniping workflows where bargain-graded cards present arbitrage opportunity.
