1884 CC cancelled die overstrikes.
Don Schmitz was the first to overstrike the cancelled die 1884 CC
Morgan dollar to raise money to renovate the CC building. (More on that here
http://goccf.com/t/90896#752839 ) Pictured below are a few examples of the souvenirs he created after finding the cancelled dies while doing the renovations to the old Carson City Mint. (The home of the Nevada State Museum)
It's my belief Don used cancelled 1878 CC reverse dies while Dan used 1879-1893 CC reverse dies.


Struck on oversized 2-ounce blanks.


Daniel Carrs gold 1884 CC cancelled die strike with matching die pair # 37.


Same #37 die set overstrike by Moonlight Mint.


Have a good day and enjoy!
