i would call the northeast document conservation center and ask them
who would appraise it for you. i have seen many ambrotypes over the years
and i think 800 seems a bit excessive, unless the person who took it is well known ...
but what do i know ...
they say that something is worth what someone will pay you for it so even if the
person who appraises it says it is worth 100$, you can easily put it on the auction site
with a hefty reserve and se
The length and shape of noses and ears, the legs and coats all say to me that these dogs aren't spaniels. Not that this is relevant to the subject of what the picture is worth.
They look pretty typical of working spaniels wearing short haircuts. They look nothing like a modern show dog. These are the real deal. My working cocker, who wears the same haircut, looks just like them only he is smaller and black all over. One thing puzzles me though and that is why are they wearing collars? Working dogs, hunter retrievers that is, shouldn't work in collars in case they get hung up.
Ambrotypes don't sell nearly as high as daguerreotypes. If it's a normal size (about 2x3 inch or 3x4 inch even) I think the offerer just likes it and wants it. I'd sell it for that and not waste time appraising it. You can do your own appraisal by seeing what similar items (animal shots on ambro or tintypes) have sold for. I bet it's less than $400. If it happens to be large, about 4x5 or larger, it's worth more. I'd sell now.
