This is just my personal appraisal of the Crowley Pedigree. It is not considered a 'high-end' pedigree because the books generally rate at cream to off-white page and have an overall dingy appearance. That aside, they are typically structurally sound and grade fairly highly. I don't recall a lot of 9.8 copies but 9.4 are found in abundance. For most of the Fawcett titles, I doubt you could ever complete a full run in high grade without have a large number of Crowley's books.
Crowley copies come in two flavors, the normal, C/OW copy and the BFU stamped FILE copy. For me, the big Fugly stamp is a total turnoff. I picked up a few early on in my collecting but avoided them after just a few copies. Some folks like them because it clearly shows what they are. I found the stamp to overwhelm the cover art to a degree it ruined the book. again, just my personal opinion.
In general, I would call the Crowley copies one of the poorest pedigrees as far a desirability but one of the easiest to find on a regular basis. I am sure that I have owned a ton of issues over the years but never hesitated to upgrade to a better looking copy if one came along, even if it had a lower CGC grade
