Is LEGO Johnny Thunder Key Chain a good investment?

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 Johnny Thunder Key Chain so expensive?
Johnny Thunder Key Chain 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.
