Using modern 90% or 22 ct melted coins is the most popular source metal for modern high quality fakes.
That is why XRF is more useful for metal analysis on ancient coins. The ancients never had access to modern electrolytic metal refining processes. You look for trace metals instead.
Cleaned up fake dies can me made by laser optic profiling to produce a digital model. A die is then cut by a spark erosion process, using that model as instructions for cutting the die. The process is automated.
A good industrial die cutter with the necessary skill is then employed to finish the die to the required standard.
This sort of technology has been around for 15 years or more.
A professional coin dealer who subscribes to the IBSCC* can access good assistance in helping him identify modern high quality fakes. That is one reason why a good professional coin dealer worth his salt can be so helpful, and make up for my lack of expertise with modern coin fakes.
* International Bureau for the Suppression of Counterfeit Coins.
I believe this organization is now known by another name.
Perhaps someone else here in the CCF can help in this regard.
