LEGO Duke DeTain Key Chain is worth approximately $10 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Duke DeTain Key Chain retired?
Yes — Duke DeTain Key Chain (854005-1) 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 Duke DeTain Key Chain gone up in value?

Is LEGO Duke DeTain Key Chain a good investment?
Duke DeTain Key Chain currently trades 73.5% above its $6 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 Duke DeTain Key Chain so expensive?
Duke DeTain Key Chain was released in 2020 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.
