In 2004 LEGO released 10 Bulk Bricks sets. The largest Bulk Bricks set from 2004 was
10161 Black Roof Tiles with a piece count of 76 and a retail price of $5.99. The current estimated value of all these Bulk Bricks sets from this year is about $191.73 which represents a 355.7% growth.
The LEGO Bulk Bricks theme provided the opportunity to purchase larger quantities of specific LEGO elements. Rather than being traditional sets with a diverse array of pieces and instructions to build a predetermined model, Bulk Bricks sets consisted of bags or boxes filled with a single type of brick or a particular element, like doors or wheels. This theme was designed for those who wanted to obtain large quantities of particular pieces without having to buy multiple sets or source them individually.
2004 LEGO Sets
2004 was a shakeup year at LEGO, coming off of 2003 with record losses. Some significant events include the release of the QUATRO System for very young children, and most notably the replacement of many long-standing LEGO colors including gray, dark gray, brown and violet and the introduction of some new colors like light nougat which ultimately became the skin tone for many minifigures. In 2004, The LEGO Group created a partnership with Ferrari and a number of LEGO Ferrari sets were released that year based on Ferrari’s Formula 1 racing cars. New themes released in 2004 included Maersk, Knight's Kingdom II and Ferrari under the Racers theme. LEGO discontinued the Adventurers Orient Expedition, the original Spider-Man theme, LEGO World City and Gravity Games.
