| MS/PR-67+ | Virtually as struck with very minor imperfections, very well struck with attractive eye appeal |
| MS/PR-68 | Virtually as struck with slight imperfections, slightest weakness of strike allowed |
| MS/PR-68+ | Virtually as struck with very slight imperfections, the strike must be virtually full. Eye appeal must be very good. |
| MS/PR-69 | Virtually as struck with minuscule imperfections, near full strike necessary |
| MS/PR-70 | As struck, with full strike |
