Apparently I have to look at each stamp under a microscope to see this kind of damage. Also, the receiver said I only sent 98 stamps. If so, there are 3 nice new US stamps on the cover, so that would make it 101. I dont think I deserve a negative rating.
The biggest problem with this 100 stamp exchange site is that if you dont send what the member collects, than you get negative feedback and remarks. Sorry I dont have everything that someone collects. I think I had enough of this exchange site.
