I am an Amateur military historian pursuing a Bachelors in International Studies and a minor in French. Originally, I wanted to be double majoring in history and archaeology with a minor in art history. However, I of course saw that jobs for these degrees don't pay entirely all that well and are hard to come by. So, in the meantime I searched for some way I could continue to connect to history through tangible objects.

My side-gig is a militaria seller. While most of my collection is connected to me and I will most likely never part with it, I do regularly part with some items throughout the year. In March I made $150 on three 16mm USMC films from WWII and Korea that I purchased at an antique store for 3 dollars. The hobby can be very very lucrative if you know what you're doing. Another good instance of this was just last weak at a flea market when I spent 20 dollars on a pair of USMC P42 Frogskin pants which are going for between 1k and 1.8K right now.

The best part about militaria dealing is that its price will almost never go down majorly and usually only increases in value. Overall, what Inwould recommend is to find an area of history that you enjoy most and find a hobby connected to it. Antiquing is what I love and I know that it can generate a good deal of side revenue. However, this is just my opinion so feel free to do as you please.
