The US Mint announced that there would be a design competition. Initially, only a few people joined. However, when the time was almost over, many artists submitted their work.
It shows that many were interested in winning the competition because of the $1,000 prize.
Eventually, Felix Schlag won the competition. The US president at that time, Roosevelt, also liked the design of Schlag as well as Nellie Tayloe Ross, the mint director.
