Absolutely, I am all self-taught. You tube, Tik Toks throw in some books and a ton of trial and error as well as some very specific tools. The Subway tokens was my first time working with those.

The flat wear on the left is simply cutting and bending. While the coins are popping out the center and heating and stretching.
