 During that period, quantities of pattern coins, restrikes, and pieces struck in different metals flowed to well-connected collectors and dealers, and Bosbyshell sold a large personal collection of such pieces shortly after leaving office as chief coiner.Although Bosbyshell returned as Philadelphia Mint superintendent from 1889 to 1894, he does not appear to have resumed his illicit activities.The relatively large mintage of about 6,000 in 1887 was due to a fad sweeping the country whereby men would present their lady friends with a coin with one side ground off and replaced by the woman's initials.
