Beginning in the mid-19th century, fraternal orders such as the Masons, Odd Fellows, Eagles, and Elks issued tokens that could be presented as proof of membership in the order (these are known as mark pennies), as souvenirs, and for gambling. Masonic pennies often feature a chapter’s name on the token, although some pennies bought as stock items from wholesalers do not. One sub-group within fraternal tokens are those made for the Ku Klux Klan, which often feature cryptic acronyms (MIAFA stands for My Interests Are For America) rather than the letters KKK since the organization was so reviled.
