About this Mod

Keys and Coins is a cosmetic and utility add-on designed to enhance your world’s visual appeal and economy systems. This mod introduces a variety of detailed 3D-styled keys and a complete set of multi-tier coins.
Features:
Decorative Keys: A collection of visually distinct keys. While they do not have built-in functions, they are perfect for use as custom textures for "Crates" in mods like Cobblemon, giving your rewards a more professional and immersive look.
New Currency Items: Includes coins made of Netherite, Diamond, Gold, Silver, Copper, and Ruby.
Event Coin: A special unique coin designed specifically for server events or limited-time rewards.
How it affects your experience:
This mod changes the base game by providing server administrators and map makers with high-quality assets to build custom economies. Players will experience a more organized and thematic trading system, moving away from using raw materials like diamonds as currency. The decorative keys allow for a more intuitive and aesthetic way to manage access to crates or rewards, making every unlock feel more rewarding.
