Which rarities carry this set's value. Share is the tier's raw cards as a fraction of the whole set. The PSA 10 premium is the median multiple over raw within the tier — cards under £5 raw are excluded from it, and a tier with fewer than three qualifying cards shows no premium rather than a misleading one.
