Thanks for the responses folks, and thanks Larry for posting some real numbers based on what you have bought.
I totally understand the purpose of the classification system was not value-based nor was it a rigorous assessment, but an attempt to better understand which figures seem more difficult to find based on peoples shared knowledge of collecting MUSCLE. My interest is not inherently financial in nature, although any discussion of "rarity" will somehow eventually be tied to value.
I have read many of the various discussions and theories behind production and the whys and hows of why some figures were not produced as much as others and I have also read that perhaps someday the Class A , B, and C lists could be refined as more is learned. Perhaps with all B figures being shifted into A or C as we learn more about the abundance of different figures.
Anyhow, the more I buy lots of MUSCLEs and collect, I certainly have the perception that certain A and B figures are more common than others, and even many flesh figures are consistently more difficult to find (not considering SC). I am really just interested in trying to learn more. It would make sense that the way figures are molded in trees, many figures would be produced in similar quantities, and it makes sense to have a few different tiers based on production. But even with all the knowledge out there, it just seems to me like the commonality of figures is really a continuum and not discrete groups. I have been buying MUSCLE maybe 4 years now, active on these boards less time than that, and I think perhaps 6-7k figures have passed through my hands, so I do not have that much first hand experience to base my perception on, but that is just how it seems to me.
Alas, I digress.......... but I am a numbers oriented nerd who loves toys and what can I say, this is the stuff that interests me!
I have started tracking those Class A figures that pop on eBay along with my price tracking, but the numbers are so few I doubt that data will be useful unless I collected it many years.
Now on to a ridiculous notion......if anyone out there could create a program that could recognize each MUSCLE figure sculpt in photographs similar to facial recognition, then we could scan EVERY SINGLE eBay auction and actually develop a hard-numbers database of the relative abundance of all A, B, and C figures!!!!!!!
