Exonumia are numismatic items (such as tokens, medals, or scrip) other than coins and paper money.

Besides the above strict definition, others extend it to include non-coins which may or may not be legal tenders such as cheques, credit cards and similar paper.

The words exonumist and exonumia were coined in July 1960 by Russell Rulau, a recognized authority and author on the subject, and accepted by Webster's dictionary in 1965.

Token coins

Many tokens were produced and used as currency in the United States and elsewhere when there was a shortage of government-issued money. Tokens have been used for both to advertise and to facilitate commerce and may or may not have a value.

Token authority Russell Rulau offers a broad definition for exonumia in his 1040 page tome, United States Tokens: 1700–1900 but lines between categories can be fuzzy. For example, an advertising token may also be considered a medal. Good For tokens may also advertise. Counter-stamped coins have been called "little billboards."

One way of parsing tokens is into these three general categories:

  • Has a "value," facilitating commerce, such as Good for (something).
  • Commemoration, remembrance, dedication, or the like, for some person, place, idea or event.
  • Of a personal nature.

Typically, catalogs of tokens are organized by location, time period, and/or type of item. Historically, the need for tokens grew out of the need for currency. In America, some tokens legally circulated alongside or instead of currency. Hard Times Tokens and Civil War tokens each were the size of the contemporary cent. Afterwards, value based items, such as Good for (amount of money), Good for One Quart of Milk, Good for One Beer, Good for One Ride… and others were specifically linked to commerce of the store or place of issue. When bent, the coin indicated the taking of a vow.

Germany

Notgeld, primarily in the form of paper banknotes, was issued in Germany and Austria during World War I and the interwar period by towns, banks and other institutions due to a shortage of money.

Latin America

Latin American coffee or plantation tokens were an important part of commerce. Many plantation owners had their own commissaries and workers used plantation tokens to pay for provisions. Many tokens were made in the United States or Europe. Plantation tokens had an array of denominations and names. The name can be the owner, their relatives or the name of the farm (or finca). Tokens had allegorical symbols to identify the owner. Tokens were used as currency when there was not enough official currency available. Workers could convert the tokens to official currency on Saturdays.
