Did I damaged this denarius?

I’got this septimus Severus denarius I cleaned it with Baking soda but I think I did it badly do you guys agree with me ?

I have no idea how it looked before so I can't say much on the transition but too me it looks like a harshly cleaned coin.

Any coin cleaned with baking soda is worse than it started off

I guess that baking soda is not the best thing to use for cleaning silver at all.  It left traces on the silver,you can try with lemon juice probably the coin will look much better. 

I cant see very much in those dark photos so I tried to provide better photos for everybody without altering lighting but with a white background for clarity. As said previously, we dont know what it looked like before but it is almost never a good idea to clean a coin harshly.

I agree 👍
