Is LEGO Cookie Monster Key Chain retired?

Is LEGO Cookie Monster Key Chain a good investment?
Cookie Monster Key Chain currently trades 246.6% 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 Cookie Monster Key Chain so expensive?
Cookie Monster Key Chain was released in 2021 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.
