Casting mold for coins, China, 1st century AD?

This would be one half of the mold, I believe. The second one would fit tightly in to it, helping to create the full coin, with its’ opposite face. The triangular and rectangular projections would fit in to corresponding depressions in the opposite mold.

Here are more examples of these, plus the finished coins, etc. (turn on translate)

That is so freaking cool! I’m always way more interested in ancient methods of production rather than the products themselves. It’s so neat how even after 2000 years, the methods for making molds hasn’t changed all that much.
