Assorted Tie Clip Set

This is a set of 8 assorted tie clips from the Japanese National Railways (JNR) era. Some were gifts from acquaintances, and others were provided by the labor union at the time.
I personally rarely wear ties, so most of them are unused. However, as they have been stored for a long time, some items may have discoloration or minor scratches.
(The tie clip in the second image, in particular, is likely silver but has some discoloration.)
Please judge the condition from the images of each item.

Since I will not have an opportunity to use them in the future, I am offering them at a low price.
Thank you for your consideration.
