The most common mistake new investors make is "Shotgun Submission." They send everything. This is financial suicide.
The Breakeven Formula
Before you send a card, do this math:
(PSA 10 Value) - (Grading Fee + Shipping) > (Raw Value)
If the equation is negative, DO NOT SEND IT.
Case Study: 2023 CJ Stroud Prizm
| Scenario | Value | Cost ($25 Fee) | Net Profit |
|---|---|---|---|
| Raw Card (Sell it now) | $40 | $0 | +$40 |
| PSA 10 (Gem Mint) | $150 | $25 | +$125 |
| PSA 9 (Mint) | $45 | $25 | +$20 (LOSS of $20 potential) |
| PSA 8 (NM-MT) | $25 | $25 | $0 (Total Loss) |
Conclusion: If this card gets a 9, you turned a $40 asset into a $20 asset (after fees). You LOST money by grading it.
The 10x Rule
Only pre-grade cards where the PSA 10 Multiplier is huge. A Prizm Base card might have a 10x multiplier ($5 raw -> $50 PSA 10). This is worth the risk. A numbered auto might only have a 1.5x multiplier. That is NOT worth the risk.
