Investment Thesis
bullish84Onix (CGC 10) is currently modestly undervalued, with rising price momentum over the last 30 days (+17.3%). Estimated fair value is $413 against a lowest active listing of $375. Valuation confidence is high based on 20-plus modeled comparable sales.
Bullish: rising prices (+17.3% over 30d) with thin liquidity and rising graded population (6.6%/mo).
Risk Indicators
- Rising graded population may pressure prices
Grading ROI & Population Trend
Is it worth paying to grade this card? A transparent profit model from the real ungraded cost and the audited graded value, plus a read on graded-supply momentum. The cost and odds levers are modeled assumptions you can adjust — not market-price pins.
Population growth slowing to 1.0%/mo — supply tightening across 7150 graded.

Adjust modeled assumptions
These are modeled estimates, not market-price pins.
- Modeled gem-grade odds: 30% chance of CGC 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.
