It seems some buyers are still in the process of figuring out how to clearly separate boards according to PM content. I've been selling my high-grade boards to BoardSort and he clearly distinguishes between green and non-green (aka "Chinese") boards only for newer boards which have smaller CPU sockets. For boards with larger (older) sockets, he has one category.



I've contacted another buyer who had only two types in his price list: green and non-green. I've sent him photos of large-socket boards that were mustard-colored and asked whether these would still be considered "non-green" (i.e. cheap). Sure enough, he responded that these would get the green grade.
