Those cards don't have the JIB logo printed on them thou I think, so obviously not a real gold card !
Pre 1998 (or somewhere around that time), only C&G part 1 & 2 was needed for a grading was it not ? without any need for an NVQ3 or AM2. So in that case it would've be easier to get grading ?; then again colleges did practical's and/or work book's so I guess that evened it out.
Not that I agree with colleges dropping practical element, I think its sickening and its not the kids fault is it.
