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 availabilty into account, instead stating occasional listings on Bricklink.

2001
There were many recolors of Toa Mata and Turaga masks that are considered hard to find, some more than others. Many of these masks may run up to $6 and more on Bricklink, but aren't included on this list compared to some of the pricier masks.

Great Hau Recolors
Several recolors of the Great Hau are considered hard to find.
 * A black, blue and white variant are each available for around US $6 and up on Bricklink.
 * A metallic gold variant is available for $9 and up on Bricklink.
 * A chrome variant is available for around US $20 and up on Bricklink.
 * A solid gold Hau is considered extremely rare. Produced in solid 14 carat gold, 30 of them were made and distributed in 2001 to employees at LEGO and contest winners. A chain ran through two holes in the slot at the top of the mask, so it doubled as a necklace.

Krana

 * A sterling silver Krana-Kal, in the Xa form, is extremely rare. 100 of them were made, and 72 were randomly packaged with Bohrok-Kal sets. ​​​​​​​No listings exist on Bricklink.

2004

 * The orange Vahi is available for US $10 and up on Bricklink, and the flat dark gold Vahi is occasionally available for US $20 and up on Bricklink.

2005

 * The pearl gold Kraahkan that rarely came with 8758 Tower of Toa is occasionally available on Bricklink for US $100 and up. Initially the set came with a flat dark gold mask, but later releases included a pearl gold variant instead. By that point, the set wasn't selling as frequently, and as such fewer new variants were produced. It is considered one of the rarest masks.

2007

2008

 * A mismold of Icarax's Kraahkan, with five holes instead of six, is considered rare.
