HistoryA character grade: shown, never part of Crystal City’s overall grade.
Missouri towns list about as much on the Register as the country (a typical Missouri town has 2.4 per 10,000 residents, the U.S. 2.4), so Crystal City’s 0.0 sits below most of its state (23% of Missouri towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C. The pre-1940 share is a Census survey estimate (±4.1 points). The founding year is the first post office, not a stated founding date; Wikidata gives 1911.

What stands out about Crystal City’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Crystal City was originally called New Detroit. The post office called Crystal City has been in operation since 1872. In the 1880s, Pittsburgh Plate Glass Company opened a glass manufacturing plant, which is the origin of the city's name. By 2008, the PPG plant property was empty and undeveloped. It was purchased by Wings Enterprises in the mid-2000s with the intent to construct an iron ore smelter. In the early 2000s, the state of Missouri forced Doe Run Company to purchase 160 homes in Herculaneum after it was found over 56% of children within a quarter-mile (0.4 km) of the plant had high levels of lead in their blood. This prompted greater concern when Crystal City engaged in discussions over building a $1 billion dollar iron-ore smelter on the land of the abandoned factory.
