How to Obtain Every Coin in Library Ferret

The Five Coins

Library Ferret registers exactly five coins: Diamond Coin, Emerald Coin, Gold Coin, Iron Coin, and Netherite Coin. Each is a distinct registry item, so treat them as separate collectibles rather than one currency with tiers you upgrade in place.

Progression Order

Work from the most common material to the rarest. Iron Coin and Gold Coin sit at the bottom of the ladder, so gather iron and gold first. Emerald Coin comes next, since emeralds require villager trading or mountain mining. Diamond Coin follows once you have reliable diamond access. Netherite Coin is the top of the chain and depends on netherite, so it comes last.

Practical Steps

1. Mine or trade for the base material for each coin.

2. Convert your materials into coins one tier at a time, starting with Iron Coin and Gold Coin.

3. Hold onto every coin you make. Because the mod registers only these five items, each coin is a finished product worth keeping rather than an intermediate you break down.

4. Use Diamond Coin and Netherite Coin as your high-value holdings once the lower coins are stocked.

If a coin does not appear in your crafting output, confirm you are using the exact item name — Diamond Coin, Emerald Coin, Gold Coin, Iron Coin, or Netherite Coin — since those are the only coin entries the mod adds.
