The first items from the Dick Clark memorabilia auction are up on eBay here.
I quickly skimmed through all 18 pages of items, so I may have overlooked something, but the only specifically game show-related item I saw is in this lot, which contains (among other, non-game-show things) a copy of The $25,000 Pyramid home game from Cardinal, the only one with D.C.'s picture on it. The great thing about that game--as the box clearly points out--is that you can also play The $100,000 Pyramid with it, which is important because the two shows are so vastly different.
