Help with value of Pink Floyd collection

I'm considering selling my Pink Floyd vinyl collection. I sold all my other vinyl albums years ago, but hung onto the Pink Floyd stuff because... well, just because. I would like to sell as a complete collection, not one here or there, but I have little idea what to ask. Can anyone in the know offer some advice?

I appreciate the humor of "Oh, it's not worth too much, but I'll give you $25".

But let me make this clear - I'm not selling yet and I haven't decided that I even will sell - this is NOT meant to generate buyers - I'm only looking for advice at this stage.

For a complete listing of what I have you can go to the website I created (link below). Note that it is fairly graphics intensive and requires Flash 6 in your browser (there is a link on the opening page to get this). If you're connecting to the Internet with a modem, you may find it quite tedious to browse through.

BTW, the website will go with the collection... I know, it's pretty lame as websites go, but it did take a lot of time to photograph the albums...
