I will buy them all day at $1000. A Model 1892 rifle in .44-40 in near 100% condition will easily bring $4000, maybe $5000 to the right person.
Tahunua is right, though. Folks do tend to overestimate condition, which is why pictures are so important in doing an evaluation, even an informal one. Still, there are old rifles that have been perfectly preserved and they do turn up from time to time, so I never assume that "it is too good to be true."
