Is this bronze disease?

[Din X]

I do not have experience with bronze disease.
It is a transfer die fake, and I do not know if the authentic coin it was overstruck on had bronze disease or if the patina broke out from overstriking and makes it look like bronze disease.
In pictures it looks powdery like bronze disease.
I do not have it in hand, will receive it end of next week.
I would remove the powder with knife, and hoping that it will stop.
Soaking in destilled water baking or chemicals to neutralize sulfided would be to much work for such a cheap fake

With best regards,

It certainly looks like BD.  Also, looking at edge of the coin in the image of the reverse it appears that much of the coin body might be soft under a thin hard crust.  So be careful with it, it might be fragile.  I would use a thin sharp pin and not a knife to clean it out.  Even a toothbrush and toothpick first.

It´s definitely BD, it appears to have been treated for bronze disease previously.

A bit late to the party, but yes bronze disease.
