Is LEGO Mermaid Gabby's Aquarium Adventure a good investment?

Mermaid Gabby's Aquarium Adventure currently trades 0.1% above its $23 retail price, and it is retired, so no new supply is entering the market.

Why is LEGO Mermaid Gabby's Aquarium Adventure so expensive?

Mermaid Gabby's Aquarium Adventure was released in 2025 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.
