Standing out is 8599 Krana-Kal, worth 8,649% more today than it cost at retail. The sets below run from 2001 to 2009. Every set below is now worth more than three times its retail price. The middle set on the list has grown 3,386%. The Accessories line is the best represented here. The mask and Krana packs of 2001 to 2003 cost next to nothing and were opened almost as soon as they were bought. Sealed ones are now scarce, and the original Toa Mata canisters like Tahu and Kopaka have grown in the same way.

Below are the retired LEGO Bionicle sets that have grown the most in value against their original retail price.
