Japanese 151 grading: Master Ball and regular variants
Japanese 151 Master Ball variants need their own sale comparisons. Gengar and Pikachu Master Ball records cannot price ordinary versions with the same number. Mew EX #205 and #208 are also separate records with different costs.
What to verify for this topic
Inspect the foil pattern closely and verify the slab label against the intended variant. Keep English and Japanese sales separate. A familiar set can still have stale or thin references, so check the latest dated sold examples and a lower-grade exit before selecting a submission.

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.
Incomplete outcome pricing in this snapshot: Gengar [Master Ball] #94; Charizard EX #201; Pikachu [Master Ball] #25. Treat their expected results as provisional.
Build a repeatable decision
Open a card record, check the exact variant and source, adjust the purchase assumptions, and save the analysis to your account. Revisit it before buying or submitting. 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 wrong regional release timing, assertions that slab prices and liquidity are locked in, and unsupported personal grading odds. 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.
