Squirrel Hide
From UnReal World Wiki
A squirrel hide is the abstract unit of value for items in UnReal World. It represents the value of one decent quality squirrel fur. When completing quests for villagers, they will often specify a reward in squirrel hides. Goods of an equal value in squirrel hides will be accepted for trade.
As arrows have a value of one squirrel hide and are more generally available than squirrel furs, they are often also considered a basic unit of currency.
