this simple old device makes 4 different designs.. Through gears, dies and a crank handle. It can not only squeeze and deform a penny [coin] it puts a design like the example Mike shows. Some can be rather complicated and very well detailed..
So, there is a die in there, gears and the crank handle. With a few simple turns of the crank the penny comes out with its design on it and a slight bend to it. It would be rather simple to cut a HR design die and incorporate it in the machine.. Maybe some combination of casting and this? Maybe we don't have a clue!
