Emeralds

Emeralds are the main money source for Minecraft Monopoly, just like how in Minecraft villagers use emeralds in their trades.

Start of Game
At the beginning, each player is given 1,500 emeralds, in the following form: 2 500-emerald notes, 2 100-emerald notes, 2 50-emerald notes, 6 20-emerald notes, 5 10-emerald notes, 5 5-emerald notes, and 5 1-emerald notes. Each player's total is constantly changing, though.

Removal of Emeralds
Emeralds are used in just about every transaction, from trading with other players to respawning after death to buying spaces to buying buildings for spaces.

Accumulation of Emeralds
Emeralds can be gained through collecting rent from other players, some Dungeon and Abandoned Mineshaft cards, collecting salary from passing Go, selling buildings, and selling properties to the bank.
