Bag of Changing

This simple pouch is deceptively small, when in actuality, it can hold an infinite amount of coins. When attuned to the Bag of Changing, not only can the pouch store any amount of currency, the user can deposit any amount of money into it and exchange it into different coins. For example, a person placing 10 gp into the Bag of Changing can exchange it into 1 pp. Additionally, the user can control how full the pouch looks to the outside spectator, making it appear like it contains but a few coins or is overflowing with wealth.
