Nobody on this site would be able to appraise the value of your books without looking at them.\n\nCheck the sites below to start getting some general ideas.

Don't know exactly, but I do know it is worth whatever somebody will pay for it!  I would ask an owner of a memoribelia shop, but get a couple quotes if you are interested in selling it.

simple the  item will be in the antique and collectables books at the library  they will answer over the phone or you could  do the reading your self then try a sell with a reserve price on e-bay

I would try Half.com for your  books. They have an extensive collection of new and used books for a reasonable price.www.half.com is a partner with ebay and you can find surprising values at this site.

Not very much unless it is signed or has something else quite special about it.  These items were made in great quanities and there are many in good shape still around.  I would doubt you could get more than 25% - %50 of the origanal purchase price for it at this time.  The best place to check the going rate on such items is EBay.

You might check the city or county of issue's Historical Society. They might like to have it displayed in a museum. They can give its approximate value, and you can donate it for tax deduction or simply let them "borrow" it for a designated period of time. And you can always try e-bay.

Yes they do, you need to go to a antique dealer and they will tell you how much they are worth...

Like any antiques or collectable, it is worth what someone is willing to pay..;in order to get an idea, I would suggest visiting a good firearms expert and requesting a valuation;

Check the following site.  Value depends on condition and mintmark for that date.  Anywhere from $10 to over a thousand dollars.

being that old they are worth something. ask a local book store.

I would look on E-Bay under "vintage magazines" or something like that and see if anyone else has same type up for auction.  See what their opening price is and if anyone has bid on it.  That would help.  It would also tell you if there is an interest in the particular magazines you have.  I've been selling some antique crystal on there and sometimes there is just no market for some of it, though, it could change in a week.

I think you should take them to an auction house and get them valued, film collators and movies buffs will fight over something like that if they are in good condition.

Yer talkin' to the old bookworm here, frequenter of used bookstores.\n\nThere is very little cash market for used books unless you follow a sales route yourself. I've watched a pittance change hands for boxes of books and many turned away because of overstocks or lack of interest.\n\nI turn mine into these bookstores for credit that allows me half off of the price of books that I buy from the store.\n\nIf you're looking for a return on the price you paid for them, your best bet is to donate them to a church or charitable book or rummage sale. They'll provide you with a receipt that you can use against your taxes, and it will be based on price you paid for the book, not what it can be resold for. Just make sure they're a 401c3 charity.\n\nSelling them on your own is the next best bet. In bulk at estate sales, thousand dollar encyclopedia sets go for $1, so you are unlikely to make much selling them by the box.\n\nGarage sale, flea market, eBay. Highlight them separately, sell them one by one or sets of one author or one genre.\n\nOr -- just trade them in and use them as credit toward future books.\n\nGood luck!

They have by now a different value than is printed on them. Go through one of the professional auction houses specializing in historic documents to get a fair market evaluation. \nOn eBay you most probably will sell too cheaply.

Buy them used, when possible.  Some online booksellers will provide descriptions of condition.\n\nhttp://www.powells.com \n(used, huge inventory)\n\nhttp://www.ebay.com \n(I've found great deals here, even on scholarly books)\n\nhttp://abebooks.com \n(for used and rare. not always the best prices, but you can use this site to determine the average price for almost any used book)
