What is the price per piece for Twin-rotor Helicopter?

Is LEGO Twin-rotor Helicopter a good investment?
Twin-rotor Helicopter currently trades 246.3% above its $13 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 Twin-rotor Helicopter so expensive?
Twin-rotor Helicopter 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.
