A quick in-category search on
ebay turned up more than 200 other listings for Scott 550, some from well known or well regarded sellers. Why bother with the rest?
Although inefficient,
ebay search generally turns up more stamps matching the Scott number than anyone would ever want to view, but it is unfortunate that some sellers never review their listings for errors:

Lack of specific descriptions should be a warning indicator. Offering uncertified perf 12 Washington/Franklin coils is a red flag.
Why worry about an undisclosed thin or hinge remnant on a "lightly hinged" stamp when so many others are available? When sellers use nonstandard abbreviations or meaningless sequences of lower case letters, don't expect them have any standard meaning. Avoid listings where any abbreviation in the title is not spelled out or defined in the body of the listing.
