Your local public library may have copies of Scott Catalogs you could review to get a better idea of when your stamps were issued. The catalogs are broken down by Country of issue and are not difficult to use. Offering to give away your stamps was a nice gesture but sometimes a public forum is not the place. If you research and get the catalog numbers for the stamps you could use your photos and try selling them on
ebay. With accurate photos and offering them as is perhaps you could find an interested buyer. Hope your stamps find a loving home.
