Hello, I see you’ve posted about this twice. I will delete the other post for you. Nice hat and I’m sure someone will drop in to comment later or within the next day or so.
That is a nice one. These are often difficult to date from a photo. It is a silk plush. What is the underside of the brim made of? Is the inside band made of leather? A rough guess on my part is late 1800s, 1890s - 1910.
