What is slug coins?

Slug coins, also known as slug tokens or slug currency, are metallic tokens or coins used by some businesses and organizations as an alternative to regular coins or bills. These tokens are usually made from brass, copper, or other metals and bear the logo or name of the organization that issued them. Slug coins are typically accepted only within the issuing organization, such as amusement parks, laundromats, or vending machine operators, and can be used to pay for goods and services.

Slug coins were popular in the mid- to late-20th century when vending machines were commonly used. These tokens were used as a way to prevent fraud and theft since they could only be used within the specific vending machine or business that issued them. Today, they are still used in various settings, but their use has declined with the rise of digital payment systems.

One notable example of slug coins is the San Francisco cable car tokens, which were used from the 1930s until 1994 to ride the famous cable cars. These coins have become collector's items and are highly sought after by collectors of transportation memorabilia. Another example is the Chuck E. Cheese tokens, which are used in the popular family entertainment centers worldwide.
