Frequently asked questions
How much is LEGO Heart (40004-1) worth?
LEGO Heart is worth approximately $20 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Heart retired?
Yes — Heart (40004-1) has been retired by LEGO and is no longer in production. Retired sets have fixed supply, which is why their prices are driven purely by the resale market.
Has LEGO Heart gone up in value?
Yes. Heart launched at $5 and now trades around $20, an increase of 307.6%. See the price history chart for how it got there.
What is the price per piece for Heart?
At its $5 retail price across 26 pieces, Heart works out to about $0.192 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Heart a good investment?
Heart currently trades 307.6% above its $5 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO Heart so expensive?
Heart was released in 2010 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
