- Mint Condition (9-10) - 1 maybe 2 corners with minimal wear to no wear to the slip - I don't see mint slips as perfect
- Very Good - Mint (8) - Some corner wear or surface scratching
- Very Good (6-7) - Corner wear, surface scratching or small marks. May have a minor crease on the back as long as the rest of the slip is mint.
- Good - Very Good (4-5) - Corner wear, surface scratching, small marks and/or minor crease on the front or back. May have a medium crease on Back, but not a medium or large crease on the front.
- Good (3) - Usually heavy marks, creases, maybe some small-medium size rips, still an easily readable slip
- Poor (1-2) - Large issues that are usually listed with the item or a combination of heavy marks, creases and rips on the same slip
