This how-to creates a Currency in the Web Console and sets up its Denominations.
Prerequisites
No prerequisites.
Create a Currency
In the Web Console, go to the Economy section and select Currency from the Content menu.

Click Add Currency. Give your new Currency a name and a Minor Unit Name. The code generates automatically, but you can overwrite it if you keep these restrictions in mind: it must be exactly 3 characters long, fully capitalized, and contain no numbers, special characters, or whitespace.

This example creates a Currency named Gold with the Minor Unit Name "Gold coin." Click Save to create the Currency.

Set Up Denominations
There are two ways to access a Currency's Denominations.

Inside Denominations, you'll see the Minor Unit you created when you made the Currency.
To add more Denominations, click Add Denomination.

This example adds two Denominations with names and values — the value defines how many of the smaller Denomination (Gold coin) equal one of the larger one (Gold ingot or Gold bar). Click Save Denominations when you're done.
Conclusion
You've created a Currency and configured its Denominations. Next, learn how to configure a Catalog to set prices for items using this Currency.
