Is LEGO Bad Cop Key Light retired?

Is LEGO Bad Cop Key Light a good investment?
Bad Cop Key Light currently trades 54.9% above its $12 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 Bad Cop Key Light so expensive?
Bad Cop Key Light was released in 2014 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.
