Frequently asked questions
How much is LEGO Onyx (8512-1) worth?
LEGO Onyx is worth approximately $38 on the secondary market today, based on current listings and completed sales. BrickStats updates this value daily.
Is LEGO Onyx retired?
Yes — Onyx (8512-1) 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 Onyx gone up in value?
Yes. Onyx launched at $6 and now trades around $38, an increase of 533.7%. See the price history chart for how it got there.
What is the price per piece for Onyx?
At its $6 retail price across 37 pieces, Onyx works out to about $0.162 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO Onyx a good investment?
Onyx currently trades 533.7% 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 Onyx so expensive?
Onyx was released in 2000 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.
