This listing is this for this old sterling silver thimble. It is signed inside but hard to read,but I can make out Mexico. I have seen this thimble for sale with a hallmark of ,Hecho en Mexico 925 It is 1" tall and 5/8" wide at the bottom.
It is very ornate with an applied sterling silver wire free form butterfly and a scalloped bottom.
If you collect thimbles this one would be a great one to add to your collection!
