Button forms pinned thru with a brass or silver shank to create a button loop are found on 18th as well as 19th century clothing. They can be covered or left plain. We have seen examples of originals as well as a waistcoat that survives with horn pin shank buttons in a private collection. They can also be found in various forms on leather breeches. In 1734 a runaway in Philadelphia was described wearing a pair of plush breeches with "Horn buttons turn'd round and tip'd with silver".
