The 29th Edition of the Blue Book of Gun Values says on page 732 "Previous manufacturer located in Copperhill Tennessee until circa 1998. Little information is available regarding FMJ firearms (including short barreled derringers and pistols) except they were inexpensive shooters and have little collectibility, except for some oddball configurations. Their production records were turned in to the BATF during 1998."
Unless it's an oddball or new in the box (NIB) you're probably looking at a value of less than $100.00.
50-100 or so
It should be marked on the gun- something like .410/ 45 Colt.
Value in good condition is $50.00-$75.00
10-50 usd

The maker of your Derringer is no longer in business. Sorry-
