is the UNO representation of the Automation type CY, also know as CURRENCY. 
A CY could actually be represented as hyper in UNO and therefore a typedef from hyper to a currency type would do. But a typedef cannot be expressed in all language bindings. In the case where no typedefs are supported the actual type is used. That is, a typedef'd currency type would be represented as long in Java. The information that the long is a currency type is lost. 
When calling Automation objects from UNO the distinction between hyper and a currency type is important. Therefore Currency is declared as struct.
