What is the value of a Charles Daly double barrel shotgun?

That would depend on condition, barrel length, whether or not it was imported by KBI ( tells age ), and most importantly what guage it is. The smaller guages are worth more. I paid $600 for my Miroku BC Charles Daly Model 500 20 Guage in good to excellant condition and would have possibly paid twice that if he had asked for it. I will add that if its an older German gun the value can get up there. The more info the better the answer.
