The gov tag was sold last month at a big convention. I think is was in Bellevue. The tag sold for $8500 last year. If you look on the WDFW web page under hunting there is a section that talks about all the auction and raffle tags.
2003 auction tags went for:
Statewide deer $8,500
Eastside elk $12,500
westside elk $11,000
Bighorn sheep $ 50,000
Moose $ 12,000
Mountain goat $6,750
