It will all depend on the age (era) make and of course condition and originality of the items. Given the description this case seems that it was made for percussion pistols rather than flintlocks and would probably post date the 1820s or 1830s. Without a doubt it's greatest value would be to someone with a pair of correct size and vintage pistols with the case and tools. I would put the value at around $500 unless there is someting special about the maker. It could be a tough sell at that price unless someone needed it for the pistols.
