Answer:

Hello, and thank you for your question! I'm not aware that the Fruit in a basket cookie jar has been reproduced, so yours may very well be authentic. Reference books show it as marked McCoy USA, and the mark should be the typical McCoy mark for the era. (60s McCoy mark, found in the section here on the website.) I hope this helps, if you are still concerned, feel free to send some pictures, and a couple measurements and ill see what else I can find. Happy hunting! Jonathan.
