Banker Scrip was a type of scrip issued by merchants but guaranteed by a local banking house. They were presumably backed by deposits of the merchant who issued them.

Municipal Scrip were notes issued by a city, county or state authority.

College Currency were notes used by business colleges in the training of their students in banking and accounting.

There were several financial panics in the history of the U.S. The Panic of 1893 was an especially severe panic that resulted in economic contraction. Some larger companies issued scrip to accommodate the temporary shortage of currency.

Endorsed notes were a means by bankers to achieve a circulation by avoiding local laws prohibiting the issue of bank notes. Minnesota was one state where the issue of notes was prohibited before statehood. Yet there were several bankers in the St. Paul area who wanted to increase the local money supply. They purchased the notes of defunct of non-existent banks for about the cost of printing them. The local bankers added their endorsement -- often a pen notation on the face or back -- and issued the notes as money.
