How much are PR 3 links worth

Ive got a 7 year old travel site with about 10 pages that are PR 3 and a bunch of PR 2s. Thinking of selling 1-2 links on each page, what kind of money could I expect from each link rented/sold per month? I have never sold links before so any help would be greatly appreciated.

Thanks

DISCLAIMER: DO NOT PM ME ASKING TO BUY LINKS ON MY SITE. THIS IS NOT A BST THREAD.

You can't really sell this link for a good amount because its only one in number.
I doubt if it will be worth more than $5.
The higher amount of high PR links you have, the high amount people will be willing to pay.

thanks for your reply but what do you mean its only 1 in number? I have lots of PR links pointing to my site and pages, in fact the site has over 10k links pointing to it. I would think people would pay more for having as few outbound links on the page as possible.

Send me your links on PM, maybe I would be interested for buying some.

People would generally pay for traffic, dont expect to get much for even PR7 link if traffic is not involved.
But of course there is an exception to every rule, if you market the advantages of PR3 to the right audience (may be DP guys?)
