CS-Odds and Evens.
In some instances Note will be printed with a F.S.N. that are either all even numbers M 24620486 M or all odd numbers M 91375911 M. For the most part this is rather common, and unless the serial number is comprised of another F.S.N. there is almost no value other than the eye of the beholder.
CS-Sequential Numbers.
When a CS-Strap of Notes are freshly printed, they are packaged in sequential order, lets say that the first note in the CS-Strap has a serial number of M 87210001 M the very next Note should be M 87210002 M and so on. These are not rare or valuable above the eye of the beholder. when you find a valuable F.S.N. in a CS-Strap, it is still rare that the surrounding or sequential serial numbers will add value, but, in some cases the eye of the beholder applies and the value is increased slightly.
