Vintage to now brooch/pin lot

There are 28 pins/brooches in this lot that are, for the most part, in decent pre-owned condition. They may show wear due to age and or use. There are a couple that are not in the best condition but could possibly be repaired. There are 9 that are marked with names such as Crown Trifari, Hobe, A. R. T. And more. I took photos of the ones that are marked and included the hallmark and or a brief description. I did research a few and some of them have a decent value. This is sold as a LOT ONLY! Cleaning and or repair may be required. As is, no returns.
There is a mermaid pin that is possibly a Georgia Mason piece, however, it is unmarked so I'm going to guess that it is a replica. If it possibly is an auth G. M. Piece, it has a resale value of $60 or more.
Brooches and pins are not my favorite thing to research and list so I gave up on trying to determine if it is or isn't auth. Lol
