I believe that your transparent shotshells were made by the Wanda Cartridge Company in Houston Texas between 1965 and 1972. Use Google's Advanced Search function with these three words as mandatory terms: wanda, plastic, shotshell. Enjoy the wealth of information that springs to availability!
Yes, those Wanda shotshells and those ALCAN metal shotshells are collectible. I don't know current prices, but
www.oldammo.com and some of the other sites that your Google search discovers may help with price information too.
