Best category for pins/buttons/pinbacks?

Hey yall, I'm always really torn on this one. I got some vintage pins and buttons I've been uploading and I never know what category/sub to list them under in Poshmark. Google suggests men or women's jewelry, but I hate limiting it gender since anyone can collect them.. I think I have then under home/other or home accents/none currently. I don't think they quite fit under art either. I wish there was a collectibles section! I'm sure I'm over-thinking it but any input would be appreciated.
