PS. I'm assuming we are meaning USA stamps.
As a picture is worth a thousand words, here is a scan of the Steiner page. Used in conjunction with the perf details on Colnect it should help.

The coil is die cut 11 and will always have the vertical sides imperf, the booklet stamps may have 1,2,3, or 4 sides imperf depending on booklet position.
EDIT. The booklets appear to be of 20 stamps in 2 columns, therefore you will get only 1 or 2 imperf sides, with the 2 being adjacent
Have you managed to sort the coils from the booklets. Did the detail on Colnect help?
Page #1540 in the Mystic album 5343 and 5345 have the same description, the difference I believe is the 5343 is a coil stanp. Anyone confirm this?

re: #5343 #5345 how are they different,how do I tell which is which?
