Adjust modeled assumptions
These are modeled estimates, not market-price pins.
- Modeled gem-grade odds: 30% chance of PSA 10 (a modeled probability, not a market price). Non-gem outcomes are valued conservatively at $0.
- Modeled grading-service fee: $25.00 per card, plus $4.00 shipping/insurance (modeled service costs, not market prices).
- Modeled marketplace sell fee: 13.0% of graded proceeds (a modeled cost, not a market price).
- Raw cost and graded value trace to the existing audited references/pins — this panel authors no new market-price value.
