ANSWER: Flashlights are definitely collectible. Plus they have an interesting history beginning with the first one invented in 1888.
Most people most likely believe that the flashlight first appeared in the early 20th century. But actually its invention occurred much earlier. The development of the flashlight went hand in hand with battery production. A portable flashlight depended upon a portable battery, which first came to market in 1888. These early batteries, used to power telephone and telegraph lines, were six inches tall, so people referred to them as "#6" batteries. Around 1896, battery manufacturers began producing a smaller battery, known today as a “D” cell.



Flashlight company batteries are difficult to come by since hundreds of companies came and went. Battery companies thrived and bought some of these flashlight makes. They knew that people could keep one flashlight for years, but they would need batteries every few months.
Battery companies began selling flashlights at cost during the 1920s to promote battery sales, causing many smaller companies to go out of business. Even Eveready, a well-known brand today, was bought by the National Carbon Company (NCC), which was Eveready's main supplier of the carbon used in making batteries. NCC also bought other flashlight companies, too. Eventually, NCC changed its name to Union Carbide, a union of carbon companies, to reflect what it had become.

While the campaign was a sales success, unfortunately the new name was not. Only Evereadys could be called Daylos. Other flashlight makers still called them flashlights so that's what the public called them.
Union Carbide dropped the Daylo name in 1921, which helps to date flashlights marked Daylo as having been made between 1917 and 1921. Daylo signs had been distributed to hardware companies across the nation. When the name charged, retailers discarded the Daylo signs and catalogs to make way for the new ad campaign. Only a few of these colorful advertising pieces remain, so they’re highly sought after by collectors.

As with other collectibles, there are rare flashlights that can sell for more than $1,000, while common ones can go for as little as $2. Generally, flashlights are, for the most part, very reasonably priced. Most people think of flashlights as being tube shaped which is the most common. There are thousands of nickel-plated or black tubular Eveready lights from the 1920s and 1930s that sell for only a few dollars.
One of the most valuable flashlights is the 1898 Eveready. It isn’t marked "Eveready," The patent dates are stamped on a metal ring around the middle of the light. There’s no switch, just a metal ring that presses against the metal band. The end caps don’t screw on, but the lens side is held on by friction and the other end cap has a bayonet latch. Most collectors will gladly pay $1,000 to acquire it.
