Brenner is probably best known for his enduring Lincoln coin design, the
obverse of which is the longest-running design in
United States Mint history, and perhaps the most reproduced piece of art in world history. His design was picked by President
Theodore Roosevelt, who had earlier posed for him in New York. Since immigrating 18 years earlier, he had become one of the nation's premier medalists. Roosevelt had learned of his talents in a settlement house on New York City's
Lower East Side and was immediately impressed with a
bas-relief that Brenner had made of Lincoln, based on the early
Civil War era photographer,
Mathew Brady's photograph. Roosevelt, who considered Lincoln the savior of the Union and the greatest Republican president, and also considered himself Lincoln's political heir, ordered the new Lincoln penny to be based on Brenner's work and that it be produced to commemorate Lincoln's 100th birthday in 1909. The likeness of President Lincoln on the obverse of the coin is an adaptation of a plaque Brenner executed several years earlier and which had come to the attention of President Roosevelt in New York. Bronze bas-reliefs dated 1907 and signed by Brenner have been identified and some sold in auctions for as much as $3,900. Charles Eliot Norton of Harvard, whom Brenner counted among his friends, gave the sculptor an unpublished portrait of Lincoln which served Brenner as a basis for Lincoln's features. He also examined other portraits. When Brenner forwarded the model of the Lincoln cent to the Director of the Mint, the design bore his whole name, after the fashion of the signatures on the coinage of other countries, notably on the gold coins which Oscar Roty designed for France. The director had the initials substituted for the name. =="Baranauskas"==
