Very dark coloration so there might be a reaction with the substrate.

I dont know, do you suggest any checking way?
as designed, the origin have layout of Cu, Niken and above is Au
I think Cu and Niken are dissolved
I guess you mean Nickel (Ni).
I just found the color strange, it is very brown like Copper in color.
i thought the copper would dissolve into the solution?
but this one is not exactly like copper but it is bubbly, i think it is the glue that has not dissolved completely
That is completely probable.
Maybe AP/Cupric Chloride might be better.
I am a bit confused about AP/Cupric Chloride that you explained above so I searched the internet about how to make it, can you tell me if the way to make it in this Video is correct?
I usually do not see videos.
What you need is HCl and a bit of corroded Copper. (Not strictly neccessary, butbit starts faster then).
Then you need an aquarium bubbler.
Pour in the HCl in a container big enough that the HCl do not splash out during bubbling.
Start the bubbler and let it run.
In a week or so the Copper behind the Gold will have dissolved and the foils will be loose.
If it is thin plating the Gold might be like blackish flakes in the bottom.
Thicker plating will leave beutiful yellow flakes in the bottom.
