Hungarian coin Istevan or Bela, cleaned?

Hi guys, I'm wondering if this coin is original and cleaned, seems like the was patina taken in a not good cleaning. What do you think? Thank you all and good night.

do you know what percentage of silver it is if its around 75% or above it could be that this coin was just found underground in a not so corrosive environment which could mean that there has not been cleaning done to it

100% absolutely, positively harshly cleaned.

Thank you guys. I think that if I want a medieval coin with patina it should cost at least 3 times more.

For this reason, I have quite a few cleaned medievals from eastern Europe.

I love the design of this coin, and have bid on them once or twice...

Yes, it is possible get them with original patina but it costs more than 100€…
