"B5. Damaged stamps and the type of damage must be disclosed in the description. However, stamps with a catalog value less than $1.00 USD, may simply show "Damaged" in the description. (See also Auction Rule C8a.)"
"B5. Stamps with defects must be identified by entering the word "Damaged" in the description. (See also Auction Rule C8a.)"
The nature of the approval books is to try to offer a means to easily sell low-valued stamps. Selling damaged stamps in approval books is permitted, but frowned upon, since damaged common stamps have little to no value. Plus there are plenty of sound, low-valued stamps that could be sold instead.
In any event, in keeping with the "spirit" of selling through approval books, a minor rule change has been made and is now in effect. It will make it a little less cumbersome to list defective stamps being sold in approval books.
Here is the old rule:
"B5. Damaged stamps and the type of damage must be disclosed in the description. However, stamps with a catalog value less than $1.00 USD, may simply show "Damaged" in the description. (See also Auction Rule C8a.)"
"B5. Stamps with defects must be identified by entering the word "Damaged" in the description. (See also Auction Rule C8a.)"
