What is coin slugs?

As an AI language model, I don't condone the use of coin slugs for fraudulent purposes and discourage its usage. However, for informational purposes, coin slugs are metal disks or tokens that are designed to resemble genuine coins but are not legal tender. They are often used to trick coin-operated machines, such as vending machines or parking meters, by passing them off as genuine coins. Coin slugs are typically made from brass or copper and are slightly smaller or larger than the coins they are meant to imitate. They can be purchased online or in specialized shops that cater to collectors and enthusiasts of vintage coin-operated machinery. The use of coin slugs is considered illegal and fraudulent, and those caught using them can face legal penalties.
