Universal Fantasy Currency adds one thing- Money!
Mobs drop coins. Villagers trade with coins. Coins can now be found in lootpools both vanilla and modded. The mod also automatically converts modded merchant trades from emeralds or whatever other currency is used into now using coins. The ultimate goal is for it to be a valuable, configurable resource for mod and modpack devs. By itself, perfect for an RPG experience.

Planned features:
- Player to player trade menu
- Integration with decorative coins and coin piles from other mods
- Configurable textures (i.e. choose in the config if you want coins to look fantasy, modern, or futuristic)
- Better textures in general
- I suppose whatever community feedback sounds valuable
