I have a collection of about 15 albums of (primarily) unused Centennial varieties and types put together by someone quite passionate about the subject. It includes some quite scarce items and everything is well labelled. It is a wonderful collecting area for those interested as there is no shortage of subgroups and it is a beautiful sight when it is displayed well.
For used bulk like pictured above, I agree to toss it on
ebay for a low start bid and see what happens but a low final value is not unexpected for something like this.
