Are you sure the 2008 set is oversized? It's been a while since I looked at it, but I thought it was regular size (39 mm diameter).
Anyway, prior year sets are available from the club Promotions Director -- see order form at:

Check with Roy Nelson (email at bottom of form) to make sure he has what you're looking for.
