Hi there, and Welcome also
I would sure be checking out the individual pins first and foremost I think. Some could be silver, or gold - vintage or enameled ones and worth a few $$$ on their own.
If you have a pic, would like to see some....even the hat may be vintage...
I went to Ebay, and keyed in
HAT PINS ( rather than Travel Pins) and here are some prices:
German Hat Pins-EBAYThere is a vintage hat there with 17 pins on it ($ 279.00) -- and even if you note some of the single pins demand some $$$. I would be checking EACH PIN OUT FIRST.
......and again WELCOME TO THE BOARD my southern neighbor !
