The Frank Rose rarity scale for chopmarked coins

Chopmarks consist of Chinese characters and/or designs, which were printed or stamped with punches on the surfaces of both gold and silver coins to signify that the stamper considered them to be authentic. According to Frank Rose, the term chopmark is said to have been first used by the English in connection with India, where the term was chappa or choppa, meaning an official stamp or seal.

Despite being an integral part of the history of the trade dollar, little information is available regarding Chopmarked coins, with Frank Rose’s rarity scale being the exception. Just as one might use a comparison site like Fool.co.uk to gather facts and compare types of mortgages online, the The Frank Rose rarity scale clarifies the scarcity of various coins, allowing collectors to better decipher their worth. Rose also goes on to describe the various basic types of chopmark within his short publication.
