If it's collectible, we scan it for hidden value.

The Undervalued Score (0 to 100)

It measures how far the cheapest common way to own an item lags behind recent top-grade sales. For trading cards that's an ungraded copy vs PSA 10; future boards use each market's top grade (e.g. CGC 9.8 comics, MS70 coins, sealed/graded games).

1. Entry price is the ungraded/raw market value. If there's no reliable raw value, we use the next grade down (PSA 9 for cards) and the item moves to the Graded filter.
2. Log scale so one extreme card doesn't flatten everyone else. A 10× gap scores 40, 100× scores 80, about 316× or more maxes out at 100.
3. Momentum (price change over time) is shown as a badge. It doesn't change the score yet.
4. No top-grade comp, no score. Items like that are listed as Unscored under their momentum note, never given an estimated number.
5. Outlier filter: single sudden spikes go on the watch list until more sales confirm them.

Reading the score

What the score can't tell you

• Most raw items will not reach the top grade. The gap is the upside if one does.
• Grading/authentication costs, fees, shipping, storage and counterfeits aren't included.
• Thin markets can move fast in either direction.
