Used stamps exchanges.

Curious as to why 4 stars - there is some duplication but you have over 100 stamps

SharonB, I added the detailed photo.
Look, here there are 108 stamps (pic. top)
But
1) 9 stamps are damaged.
2) 5 stamps are doublicates.
Thus, the lot contains 108-9-5=94 original stamps in good condition.
Club rules are offended - the swap doesn't have 100 stamps in good condition. I should be give a negative rating. But I don't want to do it for the new member. If there were less than 90 stamps, I would give a neutral rating.
The criteria for feedback within this 100stampsclub are:
5* - beautiful (stamps and envelope)
4* - good
3* - neutral (club rules were fulfilled, but...)
1* and 2* - negative (club rules weren't fulfilled)
Sincerely, Natalia

This is a classic (60-80 years of the 20th century) when the sstamps were very cheap and therefore very much and still there are many definite ones.
