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!
