Sometimes coin sites are not the best places to look for answers about coins.
In this case look at the abundant online images of column types and the names of the parts on top.

Look closely at the top of the columns / pillars.
Check for a flat rectangular or square block.
There are varieties.
I'm weak in this area, but it pertains details maybe at the top or near the top.
Some have crowns, some have just flat tops.

One thing about photos being deceptive:
On my own pictures, if I stare a bit, the details can look incuse or below the field.
But then they normalize and look raised above the field.

Vinegars have different strengths or higher % levels and those can do a better job.

I enjoy having older catalogs as they show coins and many locations that are not seen in newer editions and have older original Y#, C# and KM#.
I also enjoy one of my coins being in a KM catalog, but I'll need to go back and find which one it was as it's been some years.
Some members, or at least one of the KM staff and many contributors are in my coin club, so that's also something I enjoy about the hobby.

We often see posts asking if we think a coin may be genuine.
Usually only a picture with little or no details.
Some replies mention the need to know "Density" or "Specific Gravity".
At least two very short easy-to-do methods can be found online by searching terms like Home Density Test or Using Water to Prove Gold. Density and Specific Gravity would be another good search term.
The examples are very similar to what I do in the case of large coins like Chinese Dollars as well as many other types of coins that should be silver.
I've since found more and came back to edit saying there are many more than just the ones I began with- including another: How to Test Silver and Gold at Home

Knowing the diameter would help.
Maybe one of the half real pieces from perhaps mid 1700's?

Did you measure the coin and inside the capsule with a caliper?
What are the two measured sizes?

One coin is genuine from one seller and one coin is suspected of being a counterfeit by a different seller. My testing shows the suspect coin is more like a genuine piece instead of a fake. I was placing the coins in envelopes for storage and noticed toning around the rim of the good coin is not much different in color than the toning on the suspect coin.

KM numbers do and have changed over time.
Depending on which catalog you use, the same coin can have a different number as well as being attributed to a different source.

I have a coin like that- but mine is not genuine.
I could have made it look darker like the OP, but I just used bright lights and a more correct white balance.

I can't help but I did want to reply.
For me, the characters that go around the edge are key.
Because they are so worn off, I opt out as being too far gone.
Others may come up with better info.

Similar looking coins are FD#2301 and FD#2311 with a note "carved mother coin".
Not saying that's what the OP coin is.
Just saying the filled in square having a round hole looks similar.
Some sources may say "engraved or ancestor mother coin".
And there could be a connection to Vietnam as found online having an image looking like this one:

My first thought was artificial- kitchen chemistry- maybe in an oven?
There are some petroleum distillates that can react with a similar result.

I have these in both authentic and fake.
The photo's don't really tell me anything one way or the other.
My very first check is always at the ready to check for silver.
I suspend an N-52 magnet pair on a light thread, approach the magnets with the coin to see if there is or is not any diamagnetic reaction. I do have a space on my worksheet for specific gravity and record that as well along with other observations, tests & notes. Quality photos are taken as the good and bad coin samples are added to the binders containing the collection.
