HukeCoin

Small assortment of 20 different coins to choose from, all with no crafting recipes. There are common metals for most mods along with some more specific modded metals. I strongly recommend CraftTweaker mod, to add recipes to the coins you choose. Each coin when clicked on the ground will create a small coin pile, which can be piled on like snow ~ looks really cool in a vault or treasure room. 

(Center sack is a prop, iv'e seen some mods use a "Sack" as a higher tier currency like it's full of gold or something. Like all the coins, choose your own recipes if you want to include it.)

Full list included:

Coin piles of each type, a full block contains 8 coins.

If you want to see more added let me know in the comments :) ~Peace
