Prefix and chronological issue info wanted on these 2020 notes

Hi All

I own one of these, a CT prefix and I have photographed another one that has only an R prefix.

In the catalogue Kiet Tran provided a note with prefix DN

Does anyone have a list of prefixes for this one 200 Piso note from 2020? Specifically this one with no blind marks.

If you want to start the list I have single letter T and double letter CB.

Thanks, do you have access to a UVA and UVC light?

The reason being…on some of these notes they have only green fibres under UVA. But under UVC, some of those fibres turn red. 

My CT prefix turns red but the R prefix starts with red and green fibres and stays that way under UVC.

So it seems to me, or at least my theory is: the notes that have all green fibres under UVA are unusual. So far I haven't found this on any other note and I have checked a lot of others with this same seal variation and signatures, even from other denominations.

I don't have any UV light. That's on my wish list for this year.
