Condition Grading:
Mint (M) As new, unposted, in a pristine state. Not normally applicable to vintage cards unless found in original packets.
Excellent (E) No obvious flaws. Sharp corners, clean and if postally used, writing does not detract from appearance.
Very Good (VG) Minor defects such as album marks, light corner wear, light album marks, light signs of age and handling acceptable that do not detract from a visually pleasing card.
Good (G) Some small noticeable defects, handling and wear apparent, such as small creases, bends, marks, light postal ink and light indentations, not detrimental to image acceptable in this category.
Fair (F) Obvious creasing, corner/edge damage, marks, postal ink, staining, indentations, small tears or damp damage evident. Just about in a collectable state.
Poor (P) Incomplete, image seriously affected. A gap filler only!
