A banknote that has a serial number near to the beginning of the serie (view High serial number for the reverse case). It's necessary to know the serial interval (or its estimated), because the serie can start in any number, nonetheless generally starts at 1.
These pieces often has a higher numismatic value to others at the same condition, based to the difficulty, and the value is higher as the serie is near to the start.
Currently there are no defined conditions yet to check whether a serie is low or not. However, this website provides the guideline based on Relative amount of low and high serial number, which there are four amount of pieces that define four intervals.
General Interval
The general low serial interval are pieces within all levels, from the beginning of the 4th Level and ending of the 1st Level.
This piece, identified as
bbcv100bs-ea01-a8 has a serial interval
A00000001-A55000000 with
55,000,000 pieces (excluding damaged and not used). The interval for low serial number is
A00000001-A00007806 with

A.- First Interval (1st Level)
The interval is based on the first level of the conditions. This level can be considered the more feasible.
This piece, identified as
bbcv100bsf-aa02-a8 has a serial interval
A44400001-A90000000 (estimated) with
45,600,000 (estimated) pieces (excluding damaged and not used). The interval for low serial number level 1 is
A44402941-A44407104 with
4164 pieces. Photograph credits: José Manuel Piñeiro

B.- Second Interval (2nd Level)
The interval is based on the second level of the conditions (4.000 pieces for 90.000.000 issues).
This piece, identified as
bbcv10bsf-aa02-k8 has a serial interval
K00000001-K90000000 (estimated) with
90,000,000 (estimated) pieces (excluding damaged and not used). The interval for low serial number level 2 is
K00001001-K00004000 with

C.- Third Interval (3rd Level)
The interval is based on the third level of the conditions (1.000 pieces for 90.000.000 issues).
This piece, identified as
bbcv50000bs-ab01-a8 has a serial interval
A00000001-A90000000 with
90,000,000 pieces (excluding damaged and not used). The interval for low serial number level 3 is
A00000101-A00001000 with
900 pieces. Photograph credits: Mercadolibre: business_paraguana
D.- Fourth Interval (4th Level)
The interval is based on the fourth level of the conditions (100 pieces for 90.000.000 issues). This can be considered as the harder or least feasible.
This piece, identified as
bbcv20bs-fd01-t8 has a serial interval
T10000000-T18000000 with
8,000,001 pieces (excluding damaged and not used). The interval for low serial number level 4 is
T10000000-T10000053 with
54 pieces. Photograph credits:
