Prior to the striking of the planned production run of 500 silver medals for First Coinvestors, the Paris Mint tested the dies by producing 5 trial strikes in bronze, as seen here. Clearly, these were executed in brass or "yellow bronze," in keeping with U.S. Mint trends during the latter 20th Century. A careful comparison of the brass specimen with the silver examples confirms its trial strike status, as it displays a definitively earlier die state than seen on the silver medals.
