My father gave these to my mom in the 50's & the box is old but says My Eisenberg. I know nothing about them.

My Mom gave this little box to me its kind of worn but says My Eisenberg with a Christmas tag that I love though I'm sure its not good if people are collecting because it says from my Dad to my Mom and she wrote expensive across the tag! I just need to know about them and if I should carefully wrap them separately are they valuable or just sentimental. They're beautiful and so well made.
