Have a nice day.
Do I have to explain to my colleagues why I think it was scrubbed?
When the coin is completely soaked in a chemical bath, the entire surface is evenly stripped of the long-term patina of silver - which is a natural oxidation process.
But if the coin is only slightly wet and the pulp-cloth is immediately taken and the surface is wiped, the raised reliefs will be rubbed off and the body of the smooth coin will also lose its patina.
However, the edges and the written text along the edge under the relief will remain the original patina that the coin had.
here is a sample of your coin
Here is a principle and an unwritten rule:
*Either remove the coin completely and in detail from the original patina and wait for the creation of a new natural one
*if it does not have clay - mud - dirt - always leave the original, natural patina of the coin. It gives the coin its natural birth certificate as well as the maturity and quality of the metal
Just this example is a demonstration that inexpertly and unnecessarily tampering with the metal is a sign of impropriety and the coin loses its value.
So this is all me again in a nutshell and it's just my opinion and answer.
