Is LEGO Iron Man vs. Loki a good investment?
Iron Man vs. Loki currently trades 125.8% above its $18 retail price, and it is retired, so no new supply is entering the market.

Why is LEGO Iron Man vs. Loki so expensive?
Iron Man vs. Loki was released in 2016 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.
