Idea: minting press, which can be assigned an NBT value and unique iconography.
Reasoning: as it stands, most coins are fundementally infinite. By having a press which imparts a unique hidden nbt tag to coins it creates, it turns them from an easily farmed analogue of a basic resource, to a true currency, including the potential for counterfeit. Would be an excellent option for RP servers. As nbt data can be checked by create filters, it would allow for the creation of counterfeit detection machines, and would not impede creations such as vending machines beyond potentially needing an extra item filter.

Decorative potential: If the coins with a specific nbt tag could have different faces, instead of the current center circle round design. The inside could be set in the press itself, either through a block interaction, a gui etc. Once pressed, the coins could maintain their face in inventory, as well as when placed in a pile.

Final word: this idea may very well lay outside the intended scope of this project, however i feel as though its a good idea, and fits within the bounds of the type of content afforded by create, as well as that of a more generalized coin mod. Thanks for your time

How about a recipe for coins using said mint? As far as I know, there is no recipe for the coins, so they are practically useless!
