New: Fenimore Art Museum exhibition
This page will document what I have learned about Condition of an Item.
Originally produced in conjunction with the First Edition of The Overstreet Comic Book Grading Guide, the OWL (or "Overstreet's Whiteness Level") Card is a comic book grading tool used to evaluate paper color.
On the reverse side is the ONE (or Overstreet's Numerical Equivalent") Card, which translates the traditional letter grades into their equivalent values on a 100-point numerical grading scale. Predating today's commonly used 10-point numerical grading scale by about 10 years, the 100-point scale was an unsuccessful early attempt to apply a more scientific standard to the comic book grading process.
The OWL/ONE Card comes sealed in its original foil packaging.
WIDTH: 9.00 (in)
HEIGHT: 4.00 (in)
DEPTH: 0.10 (in)
The above color bands represent the lowest whiteness level in each OWL range. Match the color of comic book pages with the color scale on this card to find the OWL. This number is used with the ONE (reverse side) to accurately describe comic book condition.
FN60/7 means Grade: Fine, ONE 60, OWL 7.

The value of an item should be related to a few factors
Supply
Demand
Condition
Inherent cost of materials (worth)
Idea: I'd like to rate and rank the rarity of items to further inform my treasure hunt strategy.
