This is the response I got from a Blue Book editor regarding the Silver Star. Much of what he shared I did not include, just the value. Pretty close to a standard Govt Model Series 80. Of course, your mileage may vary.
The Colt's Silver Star MKIV Series 80 in bright stainless is not in our database. Colt's issued 1000 of this special edition during 1984, and it has a current retail value in the $900-$1,100 range.
I've seen prices on them from $7000.00 to $10,000.00 new in the box.

New Zealand has never issued a silver Halfpenny. Somebody has possibly silver plated it. Modified coins have no collector value.
