Monsters will randomly drop coins upon death. You can also find coins in chests. To collect coins in chests you need only right click whilst holding them, and they will be added. Alternatively, dropping them and picking them up as any other mob drop works just fine. There are 4 tiers of coins:; bronze, silver, gold and platinum. These can be used to trade with villagers. Coins will currently upgrade themselves, as follows:
- 64 Bronze coins => 1 Silver coin
- 64 Silver coins => 1 Gold coin
- 64 Gold coins => 1 Platinum coin
NOTE: In the current dev version, you only need 64 coins. Frizzil has said that it will be 100 in the future.
NOTE: You can only have a maximum of 63 Platinum coins as of now.
NOTE: You can't collect a whole stack of platinum.

- Collecting enough that your total platinum count goes over 63 results in the extra money not being registered at all, meaning you get nothing out of it. --Moppr (talk) 14:36, 3 October 2012 (MST)
When you find a NPC village, right clicking on a villager who does not use the default texture (one that has an apron of some sort) will open up the trading GUI. At the top of the GUI there is a box with the items that the villager has to offer, and underneath is your inventory. If you hover over an item, the price of the item will appear under its name. If the item is in the villagers area, the price under it is the buy price. Clicking an item will buy the item from the villager, which you can then place in your inventory. If you hover over an item in your area, the sell price will be displayed. You can click on the item and place it in the villagers area to sell it. Currently the villager's type does not affect the items, although the selling and buying rates do vary from vendor to vendor.
Village spawn rate has been increased so that they can be found more commonly. However, as with vanilla Minecraft, villages may only spawn in certain kinds of biomes (though the list of village-able biomes has been greatly expanded.) The villagers that spawn inside the villages will be given a first and last name, and, of course, a level.
 Exploitable Bugs
As villager trading in Hack/Mine is still in development, bugs can and do exist. Most are exploitable, and as such may be monitored or prohibited on servers. This section is mainly for the developers.
- If you remove only one arrow at a time from a villager selling them into your inventory, they will not charge you. This effectively allows for players to create an infinite money source if you then sell back the whole stack, although it can take some patience.
- Most items worth have a greater sell values than buy values, making them another kind of infinite currency generator.
- Sometimes when you rejoin single-player, all your armor weapons and tools are deleted
- On multiplayer, many villagers will often have all of the items in their inventory listed at "No Value". This allows players to make a large amount of money by buying all of that villager's items and selling them to another.
- Once the inventory of a villager is full, selling an item to them will fail,however you will still be given the respective amount of money anyways, allowing players to get a lot of money without much effort.
- In later versions, Frizzil has stated that upgrading to a higher grade of coin will require 100 of the lower value coin, and that the 64 required in the current dev version is a bug.
- If you take an item from a villager and place it in your inventory on dirt, you can replace dirt anywhere without having paid anything. This can be used to steal items and resell or just keep the items if you want.
If you find any more bugs with the currency system, please add them to the list above.
