Thanks Tempus for the info. I thought fully cured silicone wouldn't stick to itself? I will pickup some mold release regardless.
As far as recasting. This is an original coin found in a PC game in the early nineties. They are now quite rare. I will leave it up to the community to say yay or nay on offering them to people who want a replica when/if it comes to that point. As for now I am just using this as a learning experience.

As for recasting, if you were to be selling copies, maybe. As you have said that you might, it is a grey area.
Forgive me if this is a dumb question but couldn't you use PMC (precious metal clay) and fire it in your home oven or jewelry kiln if you've got one?
That would give a highly detailed metal coin that would certainly look excellent once polished or mildly buffed.
I had never heard of PMC before. Have done a little research since reading this and am thinking this might work pretty well for some one-off coins I have thought about making. I will do some more research before I put any money into it. I have not seen anything yet that says it can be done in my home oven.
