HOW THEY MADE A MORSE CODE MACHINE Samuel F.B. Morse and Alfred Vail developed an electric telegraph which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire.

With antiques, there are several factors: age, condition, historical significance, and uniqueness. In other words, (I give hypothetical figures since I'm not a dealer) a telegraph machine in poor condition that was one of 100,000 made might only be worth a few bucks. But the telegraph machine that announced the end of the First World War, and has been preserved in a museum, could be worth hundreds of thousands. You'd have to consult an antiques dealer to get a definite answer.
A telegraph is a machine which is used for transmitting messages in the form of electrical impulses which can be converted into data. A message sent via telegraph is called a telegramor cablegram, while someone who operates a telegraph machine is known as a telegrapher.
