LEGO Diagon Alley is worth approximately $650 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.

Is LEGO Diagon Alley retired?

Yes — Diagon Alley (75978-1) 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 Diagon Alley gone up in value?

Yes. Diagon Alley launched at $450 and now trades around $650, an increase of 44.4%. See the price history chart for how it got there.

What is the price per piece for Diagon Alley?

At its $450 retail price across 5,544 pieces, Diagon Alley works out to about $0.081 per piece. Collectors often use price per piece to judge whether a set is good value.

Is LEGO Diagon Alley a good investment?

Diagon Alley currently trades 44.4% above its $450 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 Diagon Alley so expensive?

Diagon Alley 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.
