Most people believe consecutive notes have no extra value, but there are collectors our there who may pay a premium for consecutive notes.
I believe that most collectors (& dealers) view consecutive notes as an opportunity to get a discount (& rightly so). I don't know anyone who pays more for quantity of anything. Yes, a few people do pay a premium for consecutive notes (no matter what they are) but these are usually dabblers in the hobby (& that's okay- just don't fall under the impression that this is the norm).
There are a few occasions when experienced collectors/dealers may be willing to pay a premium for consecutive UNCIRCULATED
rare notes. Devil Face notes (especially ones) are not considered that rare. They're simply popular (& that is usually what drives up their BV). Only their replacements (or change-overs & some denominations $5 or $1000 are harder to come by) and will command greater interest amongst the collecting community.
IMO: The notes definitely look about AU with edge wear (they have been circulated). It would be easier to assess their individual grades with a view of their back sides. If you like consecutive notes you may wish to sell 1 or 2 of the set of 5.
