What Year Are Polymer ₱1000 Prefixes BN–BQ Dated? (Between BM-2022 and BR-2023) [resuelto]

I’m trying to clarify the dating of the polymer ₱1000 banknotes for prefixes BN, BO, BP and BQ.

From what I have observed so far:

• Prefixes AA–BL are dated 2022 and carry the signatures of Rodrigo Duterte (RD) and Benjamin Diokno (BD).
• Prefix BM appears to be the first prefix with the new signatures of Ferdinand R. Marcos Jr. (FRM) and Felipe Medalla (FM), while the note is still dated 2022.
   

What I’m trying to determine is the transition point for the printed year on the note.

The closest prefix I have personally seen after that is BR, and that note is already dated 2023.

So my question is:

Do prefixes BN, BO, BP, BQ still carry the year 2022, or were they already switched to 2023?

If anyone has examples or photos of these prefixes, it would help a lot to confirm the exact transition point.

transition to new sign in 2022

Found BN prefix and still dated 2022

so looking for BO BP and BQ prefixes

Found the BP prefix. It is still dated 2022. So, I am still looking for the BQ prefix to confirm whether the starting prefix for 2023 is BQ or BR.

Finally I found the note with BQ prefix and the note is dated 2023 year. So the starting prefix for 2023 year is BQ. All known prefix in the Google Sheets https://docs.google.com/spreadsheets/d/1mHD-oENQXam60jJD0IzVIjidUu_c14Z3N-FH2BEeEcY/edit?usp=drivesdk
