All I know about barber chairs is what I have seen on Pawn Stars. Apparently, they aren't worth a whole lot unless they are in pristine condition.
Also, it seems that the head rest is worth almost as much as the rest of the chair. When people started shaving themselves, the head rest got tossed.
I looked on eBay. There are a lot of chairs running from very little to

. People are not lining up to buy them.
My barber has 6 old chairs besides the ones that they use. I think that they are all Koken and Kochs.
Like most things, people seem to think that anything old is valuable. Quite often, they will be disappointed. You got yours for a good price though.
I found this.
If the chair is hydraulic, it was made from 1899 until the company went out of business in the 1930s.
Eugene Berninghaus Company
The first manufacturer of barber chairs in the United States was Eugene Berninghaus. Opening his business in 1875 in Cincinnati, Ohio, Berninghaus made barber chairs and other tonsorial furniture and accessories. As his business grew, Berninghaus named his most popular barber chair the "Hercules" models. The Hercules models were made of wood and cast iron with a choice of leather or mohair plush upholstery. The wood choices included:
Birdseye maple
Oak
Cherry
Mahogany
Walnut
Perhaps one of the most well known models of Berninghaus barber chairs is the "Hercules # 58" hydraulic barber chair manufactured in 1899. It was one of these barber chairs that M.G.M. used in their famous 1960 film on time travel "Time Machine".
