Up to you. Is it $100 that you can do without?
Some would call them almost solid & consecutive;
Others would call them interesting serials.
If it was 08555855 it would be of interest to me.
I'm a big collector of $50 & I've paid huge premiums for very special notes;
AA07 555555 (only a very small number of solid first prefixes exist)
BK98 888888 & BK98 888889
Some I've been lucky enough to find are:
DA03 123321 (last prefix ladder radar serial)
CG06 123456 (ladder serial)
To me the scarcity is something I like. If I was starting out & planning on keeping just a $50 set I'd hold onto them until something better comes along. It may command a $10 premium tops if in a crisp uncirculated condition. If not I would be letting them go. Go spend your $100.
