The altering of coins dates back to the 18th century or earlier. Beginning in the 1850s, the most common form of coin alteration was the "potty coin", engraved on United States Seated Liberty coinage (half dime through trade dollar) and modifying Liberty into a figure sitting on a chamber pot. This time period was also the heyday of the love token, which was made by machine-smoothing a coin (usually a silver example such as a Morgan dollar) on one or both sides, then engraving it with initials, monograms, names, scenes, etc., often with an ornate border. Hundreds of thousands of coins were altered in this manner. They were often mounted on pins or incorporated into bracelets and necklaces. Hobo-style coin alteration could be found outside the United States, primarily in Britain, France, and South Africa.
