Investment Score
Professor's Research scores 28/100. We're withholding a letter grade because it has no PSA-10 graded price yet, so the score leans on demand signals. It's trading 14% above our fair value. It sits mid-pack in Pokemon GO by price. It trades thinly.
- Demandlimited data1.0
- Scarcity4.2
- Stability9.4
This is a snapshot of demand fundamentals, not a forecast and not financial advice. "Gaining steam" just shows that the price has moved recently, not that it'll keep moving. The score measures durability, not how a card behaves in a crash. And keep an eye out for reprints, which can crash a chase card fast no matter how high the grade. Scores compare cards within the modern era (Mega Evolution, Scarlet & Violet, Sword & Shield) — not against vintage.

Grading
Grade ladder
Confidence (High / Med / Low) is how much recorded sale history backs the price — Low means only a few sales, so treat it as directional. Prices are eBay-sold medians; ×raw is the grading premium; sales count the last 30 days.| Grade | Price | × Raw | Last sale | Sales (30d) | Confidence |
|---|---|---|---|---|---|
| Raw | $9.56 | — | $20 Apr 14 | 0 | High |
Prices are eBay-sold medians; last sale is the most recent single sale; sales count the last 30 days. Confidence reflects the full sale history behind each price — low-confidence rows rest on few sales, treat as directional.

Market
Supply & Demand
Supply is the TCGplayer listing count; demand pressure = weekly TCGplayer sales ÷ listings (soft → hot), a single-venue sell-through read. The supply-trend gauge reads eBay where we have it, with the TCGplayer listings trend surfacing as its history matures. Descriptive market context, not a forecast.
