The bottom left of each sleeve's back has an area that should be numbered with a red felt pen.  1000 copies are hand-numbered.  An additional 100-200 copies may be unnumbered, but will have a red "slash" where the number should be.  (.)The  has several examples of numbering, but it should be noted that  is most likely incorrect; not all copies seem to have been numbered by a lefthanded person, let alone just one person.
Copies 1-499 do not match those above #500, though the exact cutoff won't be known until more images are submitted.  Two people may have numbered the first 499 sleeves, though again more images are needed to form a better opinion.
Copies above #570 (since that's the earliest example we have in the 500s) are numbered by someone else, meaning two or three people are responsible for the entire 1000.  The style of writing on the high-numbered sleeves is very distinctive when compared to the low-numbered official copies and some badly attempted counterfeits.
As already stated, official copies have a red number, not blue or black as have been seen in the past.

The  is black with labels on each side.  (Record Collector claims the labels have been easy to copy.)  Any colored vinyl is an obvious fake.
Many counterfeits do not accurately copy the matrix code found in the run-out grooves of each side of the record.  This is the easiest and best way to figure out what the single is.The matrix code hand-etched into Side A of official copies is 2mm high and should read:
SP-23-A Why Don't You Trade Those Guitars For Shovels? L-31540 There is one counterfeit version that comes close, but has five errors: 1) the code is 3mm high, 2) the question mark is omited, 3) quotation marks enclose the statement, 4) the order is wrong, and 5) the dashes are missing, like this:
"Why Don't You Trade Those Guitars For Shovels" SP23A L31540 The matrix code hand-etched into Side B of official copies should read:
SP-23-B L-31540X In addition to these codes, each side also has the word Kdisc machine-stamped into the groove.
