I was able to find some information about your Civil War Token in Fuld's U.S. Civil War Store Cards (John Ostendorf, Ed.).
Charles Doscher was a grocer, located at the corner of Washington Street and Robinson Street in New York City.
The obverse die is #29500, while the reverse die is either #1053, 1054, or 1055 (it's difficult to determine which with the picture provided). Depending on which it is, it could be somewhat common (R2, with a couple thousand pieces struck) or somewhat scarce (R4, with a couple hundred struck).
That information would also be needed to determine the catalog number. It's either NY-630-V-2a, NY-630-V-2a1, NY-630-V-3a, or NY-630-V-4a.
Unfortunately I can't help you with precise value - a ballpark guesstimate would be $20 - $50 or maybe $100 on a good day with a bidding war. I could be totally wrong with that - you'll have to do some internet searching.
Inordinately fascinated by bits of metal with strange markings and figures
