Here at Toys 'N Toons we use a grading system similar to eBay's. Its very simple to understand. Its based on 5 different grading levels. They are:

​

• Brand New:  A new, unread, unused book in perfect condition with no missing or damaged pages. Straight from publisher!

• Like New:  A book that looks new but has been read. Cover has no visible wear. Dust jacket is included for hard covers. No missing/damaged pages, no creases/tears, and no underlining/highlighting of text or writing in the margins. May be very minimal identifying marks on the inside cover. Very minimal wear and tear. 

• Very Good:  A book that almost looks brand new but has been read. It still is in excellent condition. No obvious damage to the cover, with the dust jacket included for hard covers. No missing or damaged pages, no creases or tears, and no underlining/highlighting of text or writing in the margins. May be very minimal identifying marks on the inside cover. Very minimal wear and tear. ~~ Most common condition for our books. ~~

• Good:  A book that has been read but is in decent condition. May have some damage to the cover. The dust jacket for hard covers may not be included. Binding has light wear. Majority of pages are undamaged with minimal creasing or tearing, minimal pencil underlining of text, some highlighting of text, some writing in margins. No missing pages. 

• Acceptable:  A book with very obvious wear. Has visible damage to the cover but integrity still intact. The binding may be slightly damaged but integrity is still intact. Writing in margins, possible underlining and highlighting of text, can be possible. No missing pages or anything that would compromise the legibility or understanding of the text.
