Telegraph stamps are regarded by many philatelists as collectable. They are listed in most country specific catalogues though not usually in general
stamp catalogs. The French Yvert & Tellier and the latest
Stanley Gibbons catalog of British Commonwealth stamps do list these stamps.
Telegraph and Telephone Stamps of the World by S.E.R. Hiscocks (1982) and
Telegraph Stamps of the World by
John Barefoot (2013) are the only catalogues which list worldwide telegraph stamps. American telegraph stamps are also listed and described in detail in
United States Telegraph Stamps and Franks by George Jay Kramer. The first American telegraph stamps were issued by the New York City and Suburban Printing Telegraph Co., probably in 1859. The
Royal Philatelic Collection of Queen Elizabeth II has many telegraph stamps as George V was an enthusiastic collector. It includes examples of British and Commonwealth stamps as well as private companies such as Bonelli's Electric Telegraph Co. Ltd., the
Electric Telegraph Company and the
British and Irish Magnetic Telegraph Company. == The Stock Exchange forgery ==
