I'm sure you can find a place to transfer them online somewhere. But I'm writing to tell you that color film from the early 50's is valuable as stock footage, depending on content. My wife's grandfather was an avid movie maker from the late 40's to about 1960, and Getty has sold bits of his home movies for years now, again and again. Apparently footage that shows women doing domestic work, or with small children, or shopping or doing ordinary chores is always in demand. Vacations at the beach, birthday parties, etc. probably not.
