USA, Worldwide Stamp Collection  On and Off Paper 60s 70s cool collection

Worldwide Stamp collection

mostly 1960s and 1970s, some earlier

some valuable looking stamps from some small amount of research

nothing after late 70s most likely.

My grandmother used to collect stamps.  I took a few detail shots of some, not all, that are unused - pls refer to photos for details.  I did some research and it seems there could be a lot of value in some of these stamps, however - I do not have the time nor interest to research any further...so if you see stamps you think would add value to your collections, this is an interesting assortment.

***Please do not ask for any details about the stamps - I will not be going through them further.  Please refer to photos, thanks for understanding.
