Gold Coins are items that don't do anything by themselves, but exist just for a bit of fun - especially in multiplayer worlds!
Gold Coins are crafted made on a Coin Press using 1 Gold Ingot.
When a Gold Coin is held by a player for the first time, it becomes "minted." The coin gains an enchantment glint and when hovering over the item in your inventory, you can see which player minted the Gold Coin.
Multiple Gold Coins in a stack may cause the texture to update. The texture changes dynamically based on how many Gold Coins are in a single inventory slot.
Gold Coins can be useful as an item no other player can obtain, since only you can mint Gold Coins under your username.
Being a gold item, Piglins will steal Gold Coins, and they can be turned into Gold Nuggets using a Furnace or Blast Furnace.
