The most recently sold one which I could locate went for $410 U.S. dollars used.
Good rule of thumb: The value of an Edison Amberola phonograph is whatever the person is willing to pay for it. For example: if a person pays $600, then it's worth that amount to that person. On average expect to get around $300 USD (u.s. dollars), a little more or less depending on the model and cosmetic condition of the cabinet.
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.

Tesla bypassed Edison's patent by making his bulbs with a bi-pin base instead of the screw in Edison base. It was only the patent for the Edison base that could reliably be enforced at the time.
Thomas Edison tended to hold on to a particular idea too long. As a result Edison held on to the idea of using direct current instead of alternating current much too long. Edison invented the diode. When the triode was invented Edison continued to try to accomplish with the diode what the triode accomplished easily. His weakness was he did not see when an idea should be dropped.

Benjamin Franklin did not invent the light bulb but instead Thomas Edison did
He invented it because many years ago Thomas Edison created a prototype that was made of paper but burnt out quickly so he made a filament that made electricity go through and provide light. Its because of him we have light, instead of candles.
Thomas Edison had trouble in school because he had hearing difficulties, which made it challenging for him to hear and understand the lessons being taught. Additionally, Edison was known to be easily bored by traditional classroom activities and preferred to pursue his own interests and experiments instead.
In the "War of Currents" era (sometimes, "War of the Currents" or "Battle of Currents") in the late 1880s, George Westinghouse and Thomas Edison became adversaries due to Edison's promotion of direct current (DC) for electric power distribution over alternating current (AC) advocated by Westinghouse and Nikola Tesla. resources: wikipedia
Edison did not invent the first electric light bulb, but instead invented the first commercially practical incandescent light.---------------------------------------------------------------------------------------------------Yes he was afraid of the dark but Edison did not actually invent the light bulb... it was designed somewhere in the UK by Nicola Tesla. Edison refined his design to create 'the modern light bulb' ... :)!
