For those who did not see the awards - My company built them. We build livestock tools, not "awards", so we're pretty proud of the work.
We really enjoyed building those awards for the most part... Getting the polished finish right was really a trick - even with wrapping and sleeving them, avoiding scratches was HUGE headache. Not sure if you saw the vendor awards on the table in front; we did a brushed finish on those that looked awesome, but was even more work (and a budget buster). Since all show proceeds would be donated to Children's Mercy Hospital, we did the awards at cost, and actually wrote off the design, engineering, and programming expense as R & D work. We started these way back in February.
They are 3003 Aluminum Billet, 7" in diameter x 1/4" thick. The CNC work was about 12 minutes each on a HAAS VF2. The smaller logos and lettering were done on our new laser engraver (7"x7" window). Initial designs were 8" and fully CNC'd, but the cycle time was close to 30 minutes... (expen$ive!) The discs were sent to a company in Chicago who does electro-polishing. I assembled every one of the 450 awards myself on my office desk over a 5 week span. There's a pair of #4-40x1/8" screws that hold the plate in the machined recess -every one done by hand.
The aluminum inserts are anodized in 5 different colors, depending on the type of award, and Laser engraved as well. That material is actually what we use to stamp MILLIONS of Rabies Tags for dogs & cats...
(note:difficult to get great pictures, as the finish is VERY shiny, almost like chrome)
