Tie clip or bookmark

[mrs_b*s_collectibles_and_more]

Hello, 

I found this going while going through some of my dad's things.   At first I thought it was a 10 commandment tie clip, but the clip just doesn't look right. Then I thought maybe a bookmark? Any ideas? If it's not a tie clip, some people are paying much for a book mark. 

Thank you.

Found several listings that say it's either a bookmark or a pocket clip @mrs_b*s_collectibles_and_more :

Some have it listed as a tie clip, but most of the ones I found listed as a tie clip have a different style clip on the end.

This one has a clip on both ends:

Have you tried clipping to a book page, to a jacket pocket, and to a tie to see how it fits? Hard to judge the exact size/width of that clip from the pictures you uploaded.
