Tracking LEGO Set Values and Costs with CardWorth
Keep your LEGO sets, their condition and what you paid in one place, and compare them with an estimated current value.
Add your sets
Search by the set number printed on the box (for example 75192) and record the quantity and condition. LEGO box photo scans have a free allowance of 10 per day.
What the value means
Values are estimates from BrickLink sold data and show when they were last updated. Prices are refreshed on a schedule, typically every few days, not in real time.
The catalog lists 28,000+ sets. Not every set has a current market value; sets without one show as unavailable. Sets without a value are listed as unpriced instead of counted as zero.
Condition and completeness
You can record a set as new/sealed, used and complete, or incomplete. Where BrickLink data separates new from used, the estimate follows your choice. An incomplete set is not valued separately from a complete one, so treat its estimate as an upper reference.
Cost, gain and loss
If you record a purchase price, CardWorth compares it with the current estimate. Sets without a recorded cost are not counted as profit, and the comparison is not a realized return: selling costs and fees are not included.
Estimated retirement status
CardWorth shows an estimated retirement status based on set age. It is a model estimate, not a confirmed date from LEGO. Retirement alerts and LEGO price alerts are not available. Past price changes do not predict future prices, and CardWorth does not give investment advice.
Prices are estimates derived from pokemontcg.io (TCGplayer market data) and BrickLink sold data. Prices are refreshed on a schedule, typically every few days, not in real time. Not a professional appraisal. About our data
