There are 5 each of sheep, moose, bison, and 10 total elk/deer/pronghorn Governors tags, and they are auctioned at live events across the country (for the most part, some are raffled).I believe we are speaking of the same thing. I commented that outfitters could likely steer him in the right direction, which is to the auctions or raffles that you mentioned. My recollection was that there were eight tags available, but that was 10 or more years ago. Due to the higher number of tags (5 tags? or 8 tags?) and that Wyoming is not known for producing the giant rams of some other states, these permits don't tend to go for the astronomical amounts that they do in states like Montana. When I last heard about them, they were in the price range of hunting Alberta and Wyoming sheep hunts typically has better success than in Alberta. That info is 10+ years old, and could be vastly different today but worth looking into. If you want to hunt sheep, it's worth exhausting the various options.

The first sheep tag of the year sold for just over $90,000...and, as has been noted, the first moose tag sold for $60,000.
