In 1979 LEGO released 3 Dacta sets. The largest Dacta set from 1979 was
1072 Supplementary LEGO Set with a piece count of 304 and a retail price of $16.30. The current estimated value of all these Dacta sets from this year is about $100.53 which represents a 297.5% growth.
Dacta was an original LEGO theme from 1960 to 2003 that deals with all things that can be used with educational facilities, such as DUPLO and TECHNIC. Dacta was later replaced by the LEGO Education theme. Sets in the Dacta product line were exclusively developed for usage in younger aged schools so the sets typically contain a large amount of pieces for playing and learning in groups. The sets were designed to contain a higher number of bricks and elements at a lower cost.
1979 LEGO Sets
In 1979, LEGO introduced the Fabuland theme, targeting younger children with a blend of larger parts and regular LEGO bricks. The theme featured anthropomorphic animal characters and provided a storytelling aspect. This year also saw the expansion of the LEGO Space theme, with additional sets being added. Furthermore, the LEGO Castle theme was launched, offering medieval-themed sets with castles, knights, and related elements. These developments in 1979 contributed to the diversification of LEGO's product offerings.
