Those are some great photos. Very pretty and a real old-time collection. The next step would be to get a catalog and look some of those up. Condition is everything of course and if the stamps are sound, some could have value. Look up the 50 cent Colombian (scott 240, the $1 Perry(guessing scott 276) and the 12 cent Adriatic (scott 117) and see. Not a fortune, but worth something. Of course a single tear or thin can dramatically reduce the value. I didn't catch if you know the ropes of stamp collecting, but there are some basics like don't handle the stamps without tongs, and I would leave the stamps on the page. I can't be sure, but it looks like some kind of hinge was used which is a good thing. Keep us posted on what you do. You can always become a collector, you have a great start on a classic collection!
thanks you very much for your help! honestly I dont have any experience but I read that its no good to touch them so ihavent being doing that of course. You named a catalog to identify the stamps, is there any option online?
