This note is the result of a recent chance find of a scarce early catalogue of the Chetwynd collection of tokens. The book contained several bookplates and an image of Lady Chetwynd and the catalogue compiler, Thomas Sharp, along with several hundred additional illustrations of tokens. The locations of several other copies and appearances at auction are noted.
