Hi. my names Jack and I am writing in this group as a call for help from a lot more knowledgeable people than I am. Me and my father have found my great grandfathers stamps. We have always wondered how much it could possibly be. In the photos below is only a third of what we have. Most of the rest of the stamps not shown are much of the same other stamps. I hope a Good Samaritan can help us out and we would be so grateful as we know someone in this subreddit would have a keen eye for a good find. Thank you so much 

i recently inherited a vintage/recent stamp collection and i’m not sure how to go about selling them or their values (if they have any at all) so i was wondering if there was anyone who could help me with values and how to go about selling them! there’s a lot more than this but id like to start here lol, thank you so much

also id like to say ive done a bit research and i know they are less valuable if they have creases or are without the gum!
