About Basic

Basic Sets or Universal sets were part of 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.

Basic Set consists of 8 sets that ran from 1977 to 1989. As of today, 372 Texas Rangers is the most valuable Basic Set set with an estimated new/factory sealed value of $1,609.
Summary
Basic Basic Set Universal Building Set set 733 was released in June 1980, retailing for $39, but has since been retired. New, unopened Universal Building Set sets are valued at $440, while used sets can be found for $42.
