List of Rarest BIONICLE Masks

This is a list of BIONICLE masks considered the rarest. This is based on numerous factors, such as their original status as misprints, or their current availability/prominence on sites such as eBay and Bricklink. This list does not always take a mask's availability into account. For instance, a mask may not be currently available on Bricklink, and its rare status is based on past listings.
