Library Ferret Coin Tier List and What to Farm First

Ranking the Coins

Library Ferret has five coins: Iron Coin, Gold Coin, Emerald Coin, Diamond Coin, and Netherite Coin. Ranked by how early you can realistically make them, the order is Iron, Gold, Emerald, Diamond, Netherite.

What to Farm for Each Tier

Iron Coin — farm iron ore or an iron farm. This is your entry coin and the one you will produce in the largest numbers.

Gold Coin — farm gold from the Nether or a gold farm. Slightly harder than iron but still early-game friendly.

Emerald Coin — farm emeralds through villager trades or mountain mining. This is the first coin that requires real infrastructure.

Diamond Coin — farm diamonds at deep mining levels. Only start this once you have spare diamond gear.

Netherite Coin — farm ancient debris in the Nether and process it into netherite. This is the endgame coin and the last one you should attempt.

Farming Priority

1. Build an iron farm first; it feeds Iron Coin production indefinitely.

2. Add a gold farm next for Gold Coin.

3. Set up villager trading for Emerald Coin.

4. Strip-mine for diamonds to unlock Diamond Coin.

5. Only then go to the Nether for Netherite Coin.

Following this order keeps you from wasting rare materials on coins you cannot yet sustain.
