Range of Replacement Serial #s compiled from Reply to CBSL RTI 1/18 and 14/18 and E-mail reply of 2018/07/20 including information from CBSL website https://www.cbsl.gov.lk/en/notes-coins/notes-and-coins/notes-and-coins-statistics to correlate the range of issue of regular prefix with replacements.

Replace K is the Number of Replacement notes minted in Thousands. As there are sometimes small gaps between the ranges for same Date Type, the Total maybe slightly smaller than (End - Start) of replacement numbering.
The number of Replacement notes sent to CBSL among regular issue could also be smaller than the number of replacements allocated for use, as the remainder after print run is probably destroyed.

Issue M is the Total Number of regular Notes printed in Millions

Replace per K is the average Number of Replacement notes allocated per Thousands.

It has been observed that Replacement are not included sequentially.
I have an unopened pack of 100 which are all replacements which has two sequences.

There seems to be an Increase in Number of Replacement Notes used in Lower denominations. Is it caused by post UV print vanish application.

Rs. 20 Z/2 has a max of 786000. What cause to flip to Z/3 long before completing the million? CBSL Replied The selection of the replacement prefix and the serial numbers are purely business decisions mutually agreed by the CBSL and the printer.

On My Request for information on older Series CBSL replied
Information on issues after 1987.01.01 or 1996.02.01 are not available with both the CBSL and the printer. Please note that no replacement range was used in the recent production of currency notes.

In a letter dated 2018-06-22 CBSL informed Local Commercial Banks that Replacement Notes with special prefix Z will not be issued in the future and new currency note Bundles will not have an incremental progression from XXX001 to XXY000.
