Collectible grading started in 1949 when Dr. William H. Sheldon invented the 1-70 Grade Scale for coins. Later the 1.0 to 10.0 and 1 to 100 scales were added for Action Figures, Comics, Trading Cards, Video Games and more.
If you own (or want to sell) a graded Collectible, select Professionally Graded when adding an item to your collection, then select the Grading Company from the drop-down list:
You can then add the Grade, Authentication Number (all graded collectibles have some kind of control number) and any possible Qualifiers (the form will allow you to select the Qualifiers for the selected Grading Company). Qualifiers might be single selections or graded, here is an example for NGC Ancients:
The item in your collection will then look like this:
- If you add an item to your collection and later have it graded, you can edit the Collectible entry and select Professionally Graded.
- We currently have around 50 grading companies to choose from. If yours is missing or we didn't get the Qualifiers right, please let us know and we'll get it added or fixed as soon as possible!
