In 1852, the firm of Wass, Molitor & Co. began striking gold coins in denominations of $5 and $10; in 1855, they added $20 and $50 coins to the mix. According to Pioneer Gold specialist, Don Kagin, the Was, Molitor coins "...had the highest intrinsic value of any of the private coiners..." This was a dangerous path to tread because if the coins exceeded their face value, they were subject to being melted down. This may account for the rarity of these pieces today.
The 1852 Wass, Molitor $5's come in two varieties: Small Head and Large Head. Both types appear to be of similar rarity, and both are difficulat to find in high grade, primarily because of the poor quality control in the Wass, Molitor operation. The best example appears to be the PCGS MS60 from the Riverboat Collection that sold in April 2014 for $82,250.
