The rules have changed over the years (twice that I know of) so I can't really give a solid answer. I do have a recommendation however... New Graham Pharmacy has quite a few collector numbers that have been "abandoned" by the collectors due to the bad economy. Basically, the collectors just stopped getting their knives and New Graham still gets them in for every variant. I'd say that a phone call would probably land you a deal. If you choose to go this route, you will also have somewhat of a "backwards" opportunity to get CC marked knives that have already shipped (and are sitting in New Graham's showcase).
Give em a call. NGK is great folks to do bidness with. Cheers.
