Here is a quick overview of the process so you can know better if you might be interested.
1. Get sheet silver from a jewelry supplier. Costs spot plus a small premium. Riogrande is my favorite.
2. Roll it out with rolling mill if needed. (almost never is necessary, only if it comes a little too thick. Always a good problem)
3. Cut into proper size with shears. I get it in 6 inch by 2 inch strips and cut that into 3 pieces that are 2 inches square.
5. Stamp grid pattern with hydraulic press. This involves a little muscle and is the most time consuming part.
6. Print lettering with metal printer.
7. I sold most of them in sheets of 50. I cut off individuals to sell for feedback and free/slightly profitable advertising. You can do it with the shears, scissors, or bend until they snap off.
You aren't going to get rich doing this but it is a nice little extra spending money. I was able to pay off my tools and buy a couple guns with it.
If you are really motivated you can roll your own sheet from ingots with the mill and make some extra bucks.
Finished product is 2x2 inches and 50 bars.
