This PCGS label has "Bookend" designation, but other than the single digit ("4") I don't see it as a bookend. Isn't a true bookend supposed to have a sequence of multiple numbers that are the same at the beginning as at the end?
And the person who buys this note from EBay will come on here and post their bookend 41796454. Now the note is crisp, but it's just an ordinary 1995, and to me, it's a dollar. (Even with the "mislabeled holder". I guess there is a premium for those?)
I don't think it's mislabeled--I think the label means something else. The trouble is that "bookend" has at least three common meanings. One kind of "bookend" is a serial number that starts and ends with matching sets of digits, like 85700857 or 24000024. Usually the extra digits in the middle are required to be zeroes, but sometimes the term even gets applied loosely to serials like 24910324. The seller of that Ebay item is thinking of this kind of "bookend" when he points out the 4-4. But another kind of "bookend" is of interest to error collectors. If you have a note with some kind of printing error (gutter fold, inverted overprint, whatever), then the "bookends" are the normal, non-error notes with adjacent serial numbers, that were next to the error note in its original BEP strap. I'm pretty sure this is what PCGS meant when they put "bookend" on the holder: this note with serial 41796454 was certified along with a companion error note with serial 41796453 or 41796455. Apparently they got separated at some point, making this holder now look rather odd. (A third meaning of "bookend" is used by block collectors, to refer to blocks where the prefix and suffix letters match, like E..E. The Series 1995 $1's are the only series where it's possible to assemble a complete set of bookend blocks from A..A to L..L. But this type of "bookend" has nothing to do with the Ebay note.)
I ran the certificate number on the PCGS website along with the numbers before and after it. Among the group of notes are some 295 back plate errors so it appears your theory is correct.
