That particular one is from the limited edition of Case Collector Club regular member knives. Each Life or Regular member was given the opportunity to order one of those. That bone color, which they are calling XXpresso Jigged Bone, is unique (so far) to Case Collector Club knives sold directly from Case. It has been used on the 2013 Forum Knife and the three Annual Club Knives for 2013 (Life, Regular, Junior).
For the members, the shield style, blade etch, and serialized bolster are all part of the allure, as most of them collect the knives for display and not for usage. I chose not to order one since I don't like the embellishments myself.
I am assuming you picked that up on an auction site, since otherwise you'd have to be a Case Collectors Club member and would know all of that already.
