Psyduck grading: costs, variants and downside
A Psyduck search spans standalone cards, shared GX artwork, stamped promos and reverse holos. The Town on No Map entry needs its own Japanese set record; it cannot borrow prices or grading outcomes from an English card with similar art.
What to verify for this topic
Compare the same condition in raw sold records before setting a purchase ceiling. Inspect reverse-holo surfaces and any Gym stamp in the listing photographs. A lower raw reference does not establish a cheaper source of copies capable of the grade assumed by the model.

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: Psyduck #286/SM-P; Psyduck [Reverse Holo] #88; Psyduck #20; Psyduck #199. 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 an incorrect release-era claim, unsupported celebrity and print-quality explanations, and the suggestion that population shares guarantee a batch outcome. 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.
