Investment Score
Tandemaus earns a 38/100 investment score and an F grade (avoid). That puts it among the most valuable cards in Paldean Fates. Grading a raw copy to PSA-10 currently pencils about 91% ROI. It trades at a moderate pace.
- Demand3.2
- Scarcity4.2
- Stability6.1
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.

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 |

Grading edge
Grading edge
Buy raw, grade with PSA, sell as a slab. The upside if it grades PSA 10, after fee and turnaround.
Best case — the return if this card grades PSA 10, net of the $80.00 fee and a ~8-week turnaround haircut. PSA 10s happen about 50% of the time (the gem rate above); on a miss you roughly recover the raw cost.
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.
