Antique US Navy Mess Hall Aluminum retailer Plate

We've only found a few of these plates rolling around the internet. What we found was that it's from 1860 to early 1900s and it was an enlisted soldiers mess hall plate.
In era talk, it was either late Civil War or the after period in between then and WW1.
USN for “ U. S. Navy” is marked on the bottom.

It measures 9 retailer 1/2” diameter x 1” tall.

We have 4 total of these plates, each individually listed on our shop so feel free to take a look if you'd like a whole set!

All proceeds from this sale goes towards Sarge's Veteran Support in Forks, Washington which serves the homeless Veterans of the Olympic Peninsula.
