Banten or Siak

2.76g, 25.8mm
I was trying to identify this coin and came across the following Banten page first (because B comes before S).
https://en.numista.com/catalogue/pieces76366.html
The two images on that page are similar to mine but a little different, so I checked the listed references Mitchiner MWI#3963 and Millies HCM#112. The two reference images match each other but do not match the images on the Numista page or my coin.
I then found a Siak coin: https://en.numista.com/catalogue/pieces107538.html
It is also similar but different from my coin, but the Javanese translation image helped. The coin in the catalog is read from left to right with the bottom of the script along the outer edge of the coin. My coin is read with the top of the script on edge of the coin. I can translate "Su L Ta N Si (maybe Ya K)"

My questions are:
Is my coin an upside down variant of the Siak coin, or Banten, or bad counterfeit?
Is the image on the Banten page wrong and really a Siak coin with the corrupted mix of Arabic and Javanese?
Why is it when I search under shape for "hexagon" I see 5 results, but search for "hexagonal" and see 165?
The Banten page does not come up in either search since it is listed as a "6-sided" hole.
Thank you.

These Siyak coins, whether with the letters inward (on the Numista sheet) or with the letters outward (your coin), are not referenced in the Millies with hexagonal inner holes. But as they are supposed to imitate Banten coins of the 18th century, I might bet they are genuine.

Do you think the photo for the Banten coin here (https://en.numista.com/catalogue/pieces76366.html) is wrong? It does not match either reference catalog and looks more like the Siak coin.

"Pangeran Ratu" is referenced page#42 of the Millies. Unfortunately there is no picture of these coins. Banten coins pictures going from #111 to #123 are not refering to this type.
