US military insignia dies?

[Element7]

Hello,
I was wondering if anyone here had any idea what these are? I found them in a storage garage that I bought out. I think they are molds or dies but I really don't know how they would have been used. My best guess is they were used to make duplicates with a pantograph or similar copying machine as their was a pantograph in the storage unit. I think I am going to sell them off but I'm not sure how to advertise them or if they would even generate any interest.

Thanks for the help!

I think they are dies for insignia, as you've said.

The winged prop is Army Air Force officer's collar device,
and the other is for a marksmanship badge.
