LEGO Heavy-Duty Excavator is worth approximately $100 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Heavy-Duty Excavator retired?
Yes — Heavy-Duty Excavator (42121-1) 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 Heavy-Duty Excavator gone up in value?
Yes. Heavy-Duty Excavator launched at $40 and now trades around $100, an increase of 150.1%. See the price history chart for how it got there.
What is the price per piece for Heavy-Duty Excavator?
At its $40 retail price across 569 pieces, Heavy-Duty Excavator works out to about $0.070 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Heavy-Duty Excavator a good investment?
Heavy-Duty Excavator currently trades 150.1% above its $40 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 Heavy-Duty Excavator so expensive?
Heavy-Duty Excavator was released in 2021 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.
