| description | Use when identifying a PSA slab generation. Label era affects collector preference and value. |
PSA has 9 label generations. Some eras command collector premium (Old Holder era, MK qualifier eras). Identify by font, color, and cert format.
Cards in Old Holder slabs (pre-1998) command 10-30% premium on vintage. The aesthetic is collector-favored. PSA does NOT crack and re-issue Old Holders unless damaged.
