What is brickeconomy?

As an AI language model, my knowledge relates to brickeconomy.com. Brickeconomy is a website that provides a comprehensive database of LEGO sets and their current and past market values. The website not only includes information about the set's price but also details like the set's release date, theme, and number of pieces. It has a search function that allows users to find sets by theme, year, or keyword. Brickeconomy also has a price guide where users can check the estimated value of individual LEGO pieces. The website is particularly useful for collectors and investors looking to buy or sell LEGO sets.
