Mewtwo grading: expected profit versus a PSA 10 sale
Mewtwo GX #78 and Team Rocket's Mewtwo ex #231 represent different purchases. A large PSA 10 spread on one does not make it the best use of grading capital. Compare the expected-net column and inspect the lower-grade prices that produce it.
What to verify for this topic
Keep shared Mewtwo & Mew cards separate from solo Mewtwo cards. For an expensive raw copy, test the resale outcome at the grade its photographs support. A positive conditional PSA 10 result alone leaves the cost of less successful submissions unresolved.

Read the model correctly
The comparison uses a $25 PSA Value Bulk model fee and a 13% selling fee. Verify current service eligibility, declared-value limits and possible upcharges before submitting. The table excludes shipping, tax, insurance, supplies and time costs.
Expected net profit weights resale outcomes across the recorded grade distribution, applies the selling fee, and deducts raw and grading costs once. PSA 10 net profit assumes the card receives PSA 10. PSA 10 ROI divides that conditional profit by raw plus grading cost. It is not expected ROI.
Historical population shares are assumptions for this calculation, not personal grading probabilities. Missing grade-price references may use the engine's raw-price fallback; unmodeled outcomes and sparse records can materially change the result. Inspect the current card detail and replace reference inputs with your actual costs and verified sold evidence.

Build a repeatable decision

The methodology explains the model; Pro describes the available research features. A saved analysis records a decision assumption, not a realized return.
Correction — September 5, 2026: Removed the incorrect Shining Legends release year, unsupported supply explanations and a formula that treated the PSA 10 price as the value of other grades. The URL is preserved so earlier links lead to the correction. The current table replaces the historical figures with a dated, explicitly labeled model snapshot.
