I would offer the Magical Kingdom material together.
If you are using
ebay to better understand the possible value, do not bother looking at all the 'For Sale' listings, people ask silly prices for stamps because less experienced folks sometimes think that a 'stamp collection' is inherently valuable.
Instead, filter
ebay search results for only listings that have 'Sold' (check box on left hand side of
ebay search page). For example here is a typical 'Sold' listing for a Magical Kingdom of Disney Stamps listing;
https://www.ebay.com/itm/Disney-Sta...AOSwqbxaE3wkOf course the value is largely dependent upon which stamps are included; this probably explains why you are seeing a wide range of pricing.
Cautionary note; do not 'stick' the stamps into the albums. The proper mounts for large panes or sheets of stamps can be costly, sometimes surpassing the value of the stamps themselves (which may explain why some have not already been mounted in the albums). But putting them into the album improperly can remove any value they might have.
