Well, $1 per stamp, I am sorry to say, is unrealistic. Depending on condition and sheer number, a dealer will look to breaking up a collection, pull the few worthwhile and sell the rest in "grab bags" for pennies apiece.
Is there a stamp dealer in your town? [here in SF there is only one left !] They usually will buy by weight, if it is a mixed, i.e. not specialised collection. What album are they in? sometimes the pages can be more useful than the stamps ! Sometimes the publisher is long out of business and it is difficult for collectors to find the fill-in pages they need.
If it is not too heavy to tote around, make an appointment with a dealer for an appraisal. Otherwise, see if they will come to you.
Stamp magazines always advertise "we will buy your collection ! Be wary of these, at it involves you paying postage, recieving an offer that is extremely low, and just saying yes to avoid the hassle of having it back !!
Go to a stamp show !! they are interesting, and you will meet people interested in looking at your collection and give you honest advise, whether they are interested in buying it or not.
Hope this helps,
