What is the value of an original letter written and signed by Thomas Edison referencing the development of the telegraph?
An authenticated Edison letter's value depends on the rarity, condition, and content. Also whether it is typed or holographic, in his own handwriting. His classic "umbrella" signature alone can be worth $500 or more. Letters start closer to $1000 and can be many times that. Ultimately, the final value is determined by what someone is willing to pay
