Struct Currency
Represents a currency type. Every single value of Currency defines a distinct currency type. To draw a parallel with real world monetary, each Currency value represents such currencies as USD (US Dollar) or EUR (Euro), not values like $100 or €100.

[Serializable]
public readonly struct Currency : IEquatable<Currency>, ISerializableRemarks
There are two types of Currencies: capped and uncapped. Capped currencies have a hard limit on the maximum minted amount, and uncapped currencies do not have the said limit. To define a Currency you may call either of the following.
Examples
Here is how US Dollar can be represented using Currency:
var USMint = new PrivateKey();
var USD = Currency.Uncapped(ticker: "USD", decimalPlaces: 2, minter: USMint.ToAddress());
var twentyThreeBucks = 23 * USD;
// Or alternatively: USD * 23;
// Or explicitly: new FungibleAssetValue(USD, 23, 0)Constructors
