A LEGO set valuation tool that estimates portfolio marks from completed sales, recency, condition, fees, and reported sample size.

Why it surfaced

Sealed treats collectible valuation as an audit trail rather than a mystery number: its archive records sourced and timestamped observations, while each mark shows its range and comp count. It also separates live asking prices from sold comps and calculates net realizable value after marketplace fees and shipping.
