Is LEGO Sonic the Hedgehog™: Knuckles & Shadow a good investment?
Sonic the Hedgehog™: Knuckles & Shadow currently trades 99.8% above its $20 retail price, and it is retired, so no new supply is entering the market.

Why is LEGO Sonic the Hedgehog™: Knuckles & Shadow so expensive?
Sonic the Hedgehog™: Knuckles & Shadow was released in 2024 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.
