  The B in BOOKER appears to be deformed or have extra metal? I cannot tell exactly from the photograph.

  Somethimes when a type one blank planchet is being rolled through the upsetting machine to give it an upset rim, which changes it to a type two planchet, stray fragments or folds of metal on the circumference of the blank get rolled down into the surface on one side or the other. When the coin gets struck this "rolled fold" is stamped down into the coin, but you can still see a gap between it and the field around it.
  
  It is a relatively minor type of production error, but collectible.

  They originate from the blanking process. When the punch is defective it will create this fold, or burr, of metal. They're quite scarce and as CaptHenway said, minor. I can't see it in the photo either.

  Also, this is the oldest example of the error that I've seen, if it is indeed a rolling fold.

  A rolling fold is a blanking burr. It's a thin, sharp vertical extension that extends up from the edge of a blank. It is caused by a dulled or chipped blanking die. The burr is folded over during upsetting and struck into the coin. It appears on a coin as a low, broad, symmetrical tongue of metal that extends a short distance into the field or design. It is unrelated to a rim burr, the latter being a form of pre-strike damage.
  
  I can't see any defect on the coin whose image you provided. Be advised that many dealers and grading services misdiagnose rolling folds on a regular basis.
