My 1917 Moonlight Mint Peace dollar
I've seen a few of these, and the high-grade examples are spectacular looking. They do offer a slightly lustrous yet matte appearance. It is hard to describe. I hadn't seen one with blazing luster until the other day. I was visiting a coin shop with a bidboard, and it offered the following Moonlight Mint Peace dollar (for about 5X's spot).
I picked it up, and under the lights do see strong luster- more substantial than I've seen otherwise.
Here is the Moonlight Mint photo of this type:
