Nice, I'm going with this 2 for 1 banger: https://www.amazon.com/Gibson-Holders-Cookware-Electronics-DCW-B/dp/B00N1QABSQ/ref=pd_sbs_201_3?_encoding=UTF8&pd_rd_i=B00N1QABSQ&pd_rd_r=NDXTMT31GYNYGP5AD7RX&pd_rd_w=Md5je&pd_rd_wg=pPgsK&psc=1&refRID=NDXTMT31GYNYGP5AD7RX

You're very welcome.

See, "appraisal" is a very specific term in the book industry. That's a specialty service where a person/firm will look at a book page by page, inspecting the binding and pages thoroughly to come up with an official value with a little certificate. This service is usually somewhat expensive since you're asking an expert to go through a lot of work. So, when you go to a bookseller asking for an "appraisal" you're asking them if they do this very specialized task, which most booksellers don't do. That's why you just want to ask them to look at a book because you're interested in selling it (even if you're not - don't tell them that) so they'll give you a number you can add 30% or whatever to find a ballpark value.

You should check out different booksellers to get multiple estimates. Like any merchant, individuals will try to undersell you to get more profit for themselves. Nothing wrong with that - any sort of selling and buying works on that principle.

You might find out that the book isn't too valuable monetarily. My gut instinct is that this probably isn't some million-dollar find, but might be worth a couple hundred bucks maximum to a super motivated collector, and even that might be stretching it. If that ends up being the case, still take care of it. You can get acid-free plastic bags/covers from any archives store online if you want to keep dust off it.

If this were my book, I'd cover the book with an acid-free clear plastic dust jacket and put it on display (out of the sun) with something like this:
