This coin is very hard metal, Nickle/ copper alloy. Lots of annealing.

Cool, did you use a hammer and mandrel? Or folding dies.  Silver coins are much easier to do than the copper  nickel

yes, drill hole, hammer and mandrel, then in a dapping block and compressed in hydraulic press half way and turned over and compressed the other side to form the domed profile.
