Normal notes have an even border around the engraved picture on the front and back. Sometimes, when the sheet of bills gets out of alignment during printing, the note will have uneven borders, a truncated design or even part of the next note's design. Typically, misaligned notes will appear well-centered on one side and off-center on the other side.
Cutting errors happen when the sheets fail to align properly during the last stage of creating a banknote: the cutting process. Both sides of the note will be affected by this error. Typically, in order to qualify for a Cutting Error however, a small portion of the adjacent note must be visible or (when the error occurs at the edge of the sheet) a small portion of the note's design must be cut off. See the $5 bill here from series 2017a which has cutting error that affected both sides of the note. https://www.pmgnotes.com/news/artic...tting-error/
Regarding the serial, its a 5 of a kind and some casual collectors collect these types of serial numbers so sometimes will sell for low amounts over face (perhaps $2.50 including shipping) but if you search bills regularly you will notice you will come across these far more often than say a 7 of a kind/7 in a row or 8 of a kind (solid) which is why those types of bills are considered fancy serial numbers and have much more value and appeal to serious collectors. http://www.coolserialnumbers.com/Ho...lNumbers.pdfhttp://www.coolserialnumbers.com/Fa...Numbers.aspxhttps://collectiblescurrency.com/bl...rial-numbers
