The LEGO minifigure secondary market — quantified. Powered by the BrickCheck™ MMi, the only Laspeyres price index tracking collectible LEGO minifigures.
The MMi 300 is not simply priced as "1 of each of the 300 figs." Instead, each fig gets a weight based on how many lots of it were actually traded on BrickLink historically. This is called a fixed-weight Laspeyres price index — the same methodology used for the national Consumer Price Index (CPI).
$3,267,062 ÷ $2,018,244 × 100 = 161.87 — the MMi reading.
The $3.27M is not "what all minifigs combined are worth" — it's the current cost of the specific, liquidity-weighted market basket. This makes the index economically defensible: it reflects how the real market weights figures, not an arbitrary equal-weight assumption. The CPI works the same way — milk is weighted more than caviar because more people buy milk.
