I know of drawings that were the early proposals for the Roosevelt Dime designs, but there are no pattern coins known, at least none that got out of the mint. One of them has a hand holding up the torch. Others differ in the positioning of the word "LIBERTY." Google "Roosevelt Dime proposals" and you will see at least one of them. The mint still made pattern coins after 1916, but most all of them were destroyed. The trouble is there were scandals over such coins that got out of the mint, and the government wanted to avoid a repeat of that. The biggest one concerned a man named William Wooden. He was the co-author of a book on pattern coins with Edgar Adams. He had both of the 1877 “Half Union” or $50 gold patterns. He traded both of them to mint for what one old time collector told me was a “trunk full 19th century patterns." It caused quite a scandal.
