IDK, maybe by observing how it appears to work? I have 100 copper coins, and I craft it into one silver coin. I'm obviously not trading it with anyone, so where could the silver coin come from? The only possible solution (without making up imaginary invisible beings who the player secretly does currency exchanges with) is that you just smush all the coins together into a silver one.
Anyway, I originally argued in the thread I made this post in at first that higher tier coins AREN'T crafted and are instead exchanged, but my opposition in that thread convinced me that coins must, in fact, be crafted from what they're made of, since we assume the same of Minecraft, and there is no waste left
Yes, you're "obviously" not trading them with someone, that would be ridiculous. What is this, a video game? That's entirely unbelievable. Makes more sense that you "smush all the coins together." Enlightening.
