In 1977 LEGO released 5 Basic sets across 3 subthemes. The largest Basic set from 1977 was
372 Texas Rangers with a piece count of 249 and a retail price of $9.99. The current estimated value of all these Basic sets from this year is about $1,688.28.
The LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.

In 1977, LEGO released several new sets and themes, including the LEGO City theme, which introduced models of city life such as houses, stores, and vehicles. 1977 was also the year that LEGO introduced the LEGO System, which was a standardized system of bricks and connectors that allowed for more flexible and versatile building. The LEGO System included a wide range of bricks in different colors and sizes, as well as new elements such as windows, doors, and roofs. Other notable sets and themes released by LEGO in 1977 included the LEGO Space theme, which introduced new models of spaceships and alien minifigures, and the LEGO Castle theme, which expanded upon the castle sets released in previous years.
