Completed sales
Matched sold comps are the strongest signal because they show what buyers actually accepted. They carry more weight when the item identity, condition, and timing are clean.
Methodology
CollectAIO combines matched marketplace evidence, source-specific guide prices, item identity, and confidence labels so collectors can separate buyer-confirmed prices from seller asks.
Evidence stack
The app treats sold comps, active listings, and source guides differently because they answer different questions.
Matched sold comps are the strongest signal because they show what buyers actually accepted. They carry more weight when the item identity, condition, and timing are clean.
Active asks show current supply and seller expectations. When no clean sold comps exist, they can provide direction, but the page calls out ask-only reads so they are not treated as confirmed sales.
TCGPlayer, Cardmarket, StockX, LEGO condition-specific values, and other source guides can support a value when they fit the item and condition. They do not replace matched comps when comps are stronger.
Confidence labels
CollectAIO confidence labels are meant to show how hard to lean on the current value before buying, selling, trading, or adding an item to a collection.
Recent, well-matched evidence agrees across the best available sources. Sold comps, guide prices, and active supply point in the same direction.
The market read is usable, but one input is thinner: fewer recent comps, older evidence, or a source mix that needs a little more review.
The value is useful as a starting point, not as an anchor. This happens with ask-only markets, thin sales, stale comps, or hard-to-distinguish variants.
Guardrails
Collectibles are noisy. Naming, condition, sealed status, grades, restocks, and marketplace quirks can all move the read. These guardrails keep the number useful without overstating it.
Use the evidence
The value, source mix, matched listings, confidence label, and latest refresh context are meant to be read together.
