Is LEGO BB-9E Key Chain retired?

Is LEGO BB-9E Key Chain a good investment?
BB-9E Key Chain currently trades 27.4% 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 BB-9E Key Chain so expensive?
BB-9E Key Chain was released in 2018 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.
