What is the price per piece for Toa Kongu?

Is LEGO Toa Kongu a good investment?
Toa Kongu currently trades 869.6% above its $10 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 Toa Kongu so expensive?
Toa Kongu was released in 2007 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.
