There has been noted an increase in the number of damaged stamps being offered in approval books. On March 29, 2018, we changed (simplified) the rule regarding selling damaged stamps in approval books.
Here is the rule:
"B5. Stamps with defects must be identified by entering the word "Damaged" in the description..."
Damage includes: repairs, thins, creases, pulled or torn perforations, scuffs, tears, stains, extraneous writing or markings in ink or marker (other than owner/authentication marks), etc.
Sellers, of course are welcome to add a more in-depth description of any damage if they wish.
ALL damaged stamps must be notated as such. Make sure that this is done. Damaged stamps not so identified are considered to be in sound condition, and are subject to a buyer dispute for being "not as described".
One other thing of note is creating approval books with the stamps on white pages. White paper offers little contrast for buyers to clearly see the stamp's perforations. While most sellers use dark-colored (black is usually best) pages to create their approval books, those using white pages are asked to convert to darker paper. It may also help your sales when buyers can see what you want them to buy.
We appreciate everyone's efforts to help make the sales platforms operate as efficiently as possible.
