Uykucu's Coins

This release introduces the full coin progression system, expanding the currency tiers from copper up to diamond.

Players can upgrade coins in the following order:

Copper → Silver → Gold → Emerald → Diamond

Each tier can be converted using right-click interactions, with reverse conversion available via shift + right click. The system is fully inventory-safe, ensuring that no items are lost if the player’s inventory is full during exchanges.

This version establishes the core economy foundation and is intended to be stable and ready for use in servers and modpacks.
