Small Collection Need Help With Value

Hello everyone, a little help please. I have received a small stamp collection from my father, and am not sure of the value of it, so, any help you could bring would be appreciated. Also, just so you are aware, I am not currently interested in selling it, I just want to know it's worth. Lastly, if you need more pictures or more detailed pictures I can upload those for you. Thank you! :)

(Note: I'm not 100% sure how those pictures will come out... I hope they're good.)

Welcome to the forum. I see the prices are listed on the glassine envelope they are in. Dealer price to a collector.

Very little value if sold as they are common and most are probably low value foreign mint or cancelled to order stamps. CTO- A genuine mint stamp that has been cancelled and sold to collectors.
