Every year, Upper Deck, Donruss and Topps give collectors some very cool freebies at the Hawaii Trade Conference, which was held in Phoenix this year. I wrote about what was given away in a recent blog and promised I'd update some of the values after more items hit the market.

While Topps didn't give anything away during its Meet the Industry segment, the Allen & Ginter cards given away at the Topps retailer party are arguably the hottest items from the conference. Remember, this set features Hall of Famers and the cards are sequentially numbered to just 30. A Walter Johnson sold for $132.50, while a Ty Cobb sold for $70, with Thurman Munson, Jimmie Foxx, Lou Gehrig, Honus Wagner, Jackie Robinson, Cy Young, Christy Mathewson, Tris Speaker, Mel Ott and George Sisler and Rogers Hornsby and Roy Campanella all selling in the $40-$50 range. The only semi-duds from the set appear to be Pee Wee Reese and Johnny Mize and they are selling for $30. Not bad for something that was given out as a three-card pack just for showing up.

Donruss' Black Boxes are always one of the most sought-after items at the conference and this year is no different. The boxes have seven cards, all of which are 1-of-1 printing plates, with two autographs per box. Even several weeks after the conference, only roughly 20 of these appear in the closed auctions on eBay, which tells us how tough they are to get sealed. The bust was strong enough that most people opened their boxes to see what autographs were inside so this will be a scarce sealed box in the future. Boxes started out right around the $200 level and have settled slightly to around $175. I would expect these prices could rise a little in the near future since there will be very few available (only six currently listed in the active items). There haven't been a lot of the signed printing plates listed individually, but a Tony Romo sold for $218 a week ago.

Upper Deck gave away a ton of sealed boxes at its Retailer Reception, but that's impossible to track since they are identical to other wax boxes. The Meet the Industry boxes included three cards, including a multi–signed card in the middle. The highest signed card I've seen was a Carl Yastrzemski/Bobby Orr single, which sold for $169. There are ton of very cool combinations with these and many are selling in the $80-$100 range, including Peyton Manning/Danny Granger, Ken Griffey Jr./Chad Johnson and Kevin Durant/Felix Hernandez. I've also seen a Patrick Kane/Joakim Noah and a Al Horford/Mark Teixeira/Kovalchuk triple autograph, which both sold in the $60 range.
