Mew grading: correct the search before comparing returns
A search for Mew can also return Mewtwo. This correction retains records whose names contain Mew as a separate word, including the shared Mewtwo & Mew card. A Mewtwo-only result provides no evidence about a Mew purchase.
What to verify for this topic
Separate Holon Phantoms foil variants and unusual promotional distributions from ordinary set cards. A rare promotional record is not a comparable for a widely available Mew ex. Check the exact distribution and language before using any quoted raw or slab value.

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: Mewtwo & Mew GX #SM191; Mew Ex [Ultra Ball League] #151; Mew [Holo] #111; Mew ex #232. 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 Mewtwo-only cards accidentally included by substring matching, unsupported release dates and fee-adjusted claims based on fee-free figures. 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.
