Are old National Geographic Magazines worth anything?

The National Geographic Society in Washington, D.C. has published and circulated National Geographic Magazine every month since January 1896 (except for the years 1897 and 1917 when the magazine was published every other month). Nine issues were published between 1888 and 1891, before the magazine went monthly in 1896. Between 1891 and 1895, 27 so-called "brochures" were produced, making a total of 36  early publications. In those early years, the magazine covers were a red brick color. Altogether, there have been 6 different color designs up to the present.
