Discuss LindaRuth's answer to: Sasha & tasha trifari pins. can pins be authentic if they are not signed on the back and have no silver marking?

My advice is that you go to eBay - community - discussion forums - Jewelry and ask your question there. There are two jewelry boards, one for fine jewelry like gold and the other for costume jewelry.  Ask on the board for costume jewelry and be able to show them a picture. these people are very knowledgable and friendly.  They have helped me many times over the years.
