Biblioteca Condumex Medal. 10th Anniversary (1975)

This silver medal commemorates the 10th anniversary of the Condumex Library in 1975. It refers to what is today known as the Center for the Study of the History of Mexico, an important documentary collection founded by the company Condumex.

The Condumex Library gathered one of the most valuable collections of historical documents in the country, with archives, manuscripts, and rare books on the history of Mexico from the Conquest to the 20th century. It is a notable example of corporate cultural patronage.

Designed with the initials J. R. L., the piece celebrates the first decade of this historical research center. Medals for the anniversaries of cultural institutions document private support for the preservation of documentary heritage. The minting of this commemorative issue was entrusted to medallic workshops or to the Mexican Mint.

The "Biblioteca Condumex. 10 Aniversario" medal was struck in 1975. It is made of silver, measures 38.49 mm in diameter and weighs 30.94 grams, the work of engraver J. R. L..

Because it is a silver medal, its value has a floor: its precious-metal content (30.94 grams). Above that, what drives it higher is condition, how short the issue was, and interest in the subject it commemorates (Biblioteca Condumex. 10 Aniversario). A piece with no wear and its original case is worth considerably more than a mishandled one.
