I found 1960s Mickey and Minnie salad serving set

[boomer1961]

About a year ago I was at my mother's for dinner and she brought out this Mickey and Minnie salad fork and spoon. I was shocked. My mother's not into Disney at all, so I asked her where she got them. She said my aunt brought them back as a souvenir from DisneyLand ... in 1965!!! They're still in the orginal box. She had never used them!!! Are they worth anything? How can I find out their value?

You don't have a picture do you? I love old stuff like this and would like to see what they look like.
