What is the price per piece for U.S. Flag?
At its $3 retail price across 35 pieces, U.S. Flag works out to about $0.086 per piece. Collectors often use price per piece to judge whether a set is good value.
Is LEGO U.S. Flag a good investment?
U.S. Flag currently trades 400.7% above its $3 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 U.S. Flag so expensive?
U.S. Flag was released in 2003 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.
