Up for bid is a One Troy Ounce .999 fine Silver Medallion to commemorate the first flight of the C-17 Globemaster III. It comes with the COA (As seen in picture) and says it was minted exclusively for McDonnell Douglas. The C-17 made its historic first flight Sept 15, 1991. Currently Boeing now produces the C-17 Globemaster III. This September 15th celebrates 20 years of the C-17- this little piece of history would make a great addition for anyone that collects C-17 memorabilia. Please feel free to contact me with any questions prior to bidding. Thanks for looking and Good luck bidding!
