Rock Specimens - 42 Types - 100-Year-Old Rock Specimens / Educational Materials - Rare

Main Mineral and Rock Specimens
A collection of 42 mineral, rock, and fossil specimens.

I inherited these from an acquaintance but they have been unused since. I am listing them for someone who can take them over and utilize them.

The publisher was Nihon Kobutsu Kyozai Sha. Considering these were rock education materials from 100 years ago, they may hold a different kind of value.
Rocks themselves do not age, so this may be of interest to those interested in historical materials. Please take a look.
The approximate size of each specimen is 3 cm.
