Yes I know that I want to trade them but I had no clue where, how or even a decent guess what the trade value could be. My own about 7 hours of research lead to guesses between 250 € to high 4 digits due to me never having bought, sold or traded any British stamps.
I wasn't being funny, or smart, rather trying to elucidate what you were after,
(help us, to help you)
Had you said "I wish to trade these stamps for circa €250 to €9.900. am I in the ballpark?"
Then we could have offered you advice from our personal experience.
Bear in mind collectors often request appraisals, and as it sometimes doesn't meet with their prev assumptions from Catalogue values, they feel insulted.
Catalogue values are for stamps in mint, or very good condition,
broad spectrum stamps on a page can hide thins, tears, missing teeth, stains, ad nauseum.
All the members here offer the truth with respect, you have a nice, eclectic set of stamps on page, certainly attractive for postmarks etc, but from what I can see, I'd echo Bobby's appraisal at max $50.
There may indeed be a special stamp hiding amongst that lot, but from a distance, how are we to tell.?
"Don't know what to do with them" suggested to me, you may consider giving them away, donating them to a club, beginning collecting yourself. or whatever. All requiring different advice.
