I have recently been approached to sell my matchlock arquebus. I am considering it, but am at a bit of a loss regarding what a reasonable price might be.

Unfortunately I don't know much about the piece as I originally bought it to help a friend out, and have never used it.

How do I go about determining it's worth? Any help or suggestions would be greatly appreciated.

Well, that depends on many factors. One, who made it. Two, what sort of condition is it in? Has it ever been fired? What sort of money have you got in it?
