Vintage black/white/gold apple shakers

Can anyone help me with the value on these shiny vintage ceramic salt and pepper shakers? They show two halves of an apple (a moral reminder?) in black and in white with shiny gold leaves on top and the inner seed portion "sketched" in before firing. They say, "Made in Japan" and must be at least 40 years old. My mother carefully wrapped them in plastic wrap, do you believe it? She wanted to keep them "fresh", I guess! They are in "like new" condition as you can see. Any idea of how much these are worth? Thanks for any direction you can give.
