Credit reference names implementation question

Hi All,
First I wish you a Happy new year.

Question: I am coding a hierarchy of classes for representing credit reference names, and I am hesitating between two alternatives. I need your opinions.

Both alternatives start with this common structure implemented using the composite pattern:
Abstract base at the root of the hierarchy: CreditReference
Derived from it are SingleReference and BasketReference, where BasketReference is the composite.

Now the question, would you have SingleReference as a concrete class, and every new name would be an instance of it, or would you go with an abstract class with every new name being a concrete class as it is done with currencies. Of course, in the second case I would provide some macros allowing to automate the generation of the code for new names.

Or any other suggestion.
Thanks
