Is LEGO Arin's Battle Mech retired?
Yes — Arin's Battle Mech (71804-1) 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 Arin's Battle Mech gone up in value?

What is the price per piece for Arin's Battle Mech?
At its $16 retail price across 104 pieces, Arin's Battle Mech works out to about $0.154 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Arin's Battle Mech a good investment?
Arin's Battle Mech currently trades 18.8% above its $16 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 Arin's Battle Mech so expensive?
Arin's Battle Mech was released in 2024 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.
