Why didn’t this Sell?

I’m not exactly sure where I bought these things. I believe they were in a box of stuff I bought at Strickers Auction. I’ve had a variety of people tell me they were different things..

Some have said they are upholstery pins.

I thought they looked like fancy push pins.

You know the kind you used for bulletin boards? What do you think they are?

Do I have them totally categorized wrong?
