Unless it's a repro.,it's worth keeping and should have some type of value.Many are worth hundreds and some are worth a few thousand.They were made in many different shapes.Does its name(ball and claw)fit the shape of the bottle?Most all American bitters bottles date from 1862-1906.The "Revenue Act Tax "on liquor began in 1862,by 1906 the Food and Drug Act placed restrictions on the sale of "bitters".There are over a thousand known types of bitters and a colored bottle is worth more than a clear bottle of the same bitters.There is a book "For Bitters Only" by Carlyn Ring,you could refer to that.There is also a newsletter for collectors"The Bitters Report" p.o.box 1253,Bunnell,Fl.,32110.How about a pic.?
