I do not know your setup, and you may be way ahead of me in your equipment and expertise. But I do have a very simple way of forcing an iPhone (or other) to focus on a coin. Since the phones are programmed to focus on the nearest thing, you lift the coin above the surface behind it making the phone HAVE to autofocus on the coin. I use this a lot and have had a lot of people on another forum use it and comment on how well it works. The only two requirements are the note on elevating the coin and using the timer function to take the pictures.

My original inspiration for developing this was CCF member and friend Darth Morgan in this original thread from years ago:

Although I never played with the lighting like he did b/c some of his pics in that thread are just amazing.
