In 2005 LEGO released 3 Factory sets. The largest Factory set from 2005 was
5526 Skyline with a piece count of 2747 and a retail price of $129.99. The current estimated value of all these Factory sets from this year is about $1,138.18 which represents a 474.3% growth.
The Factory theme was introduced in 2005 and was powered by LEGO Digital Designer (LDD), a free LEGO virtual building program for the computer. Using the LDD people could design their own 3-D LEGO virtual model, and submit it for purchase using the LEGO Shop-at-home. The Factory platform was also designed to allow users to view and purchase other users custom creations. Once ordered, these Factory sets came in special packaging that showed the model as well as all included LEGO elements needed to build the design.
2005 LEGO Sets
2005 shaped up to be a significant year for LEGO collections. Starting with the fact that LEGO System celebrated its 50th anniversary, we also saw a LEGO set designers change their techniques in set designing. 2006 marked the year that the skin color of the Star Wars minifigures changed from yellow to light nougat which also continued to various other future licensed themes. While this was a simple change, the value of sets saw high growth. 2006 introduced the LEGO City theme which replaced the Town theme, as well as Tiny Turbos under the Racers theme. However, in 2006 LEGO did discontinue Alpha Team and Baby.
