The option Coin of Settings allows you to modify and create new currencies that you can use for payment.

Once you select the currency you want to modify or select New currency, you will be able to give it a name, enter the number of decimals, the initials or symbol of the currency, and configure whether these initials go before or after the figures.

You can also create new pieces or denominations that correspond to the values of each coin or banknote of the currency.
