Is this 10,000 Pesos (Piedra de Tizoc) a satin finish coin?

Is this a proof or satin finish coin? The auction site says it's a proof, yet I doubt.

The last two satin finish images are from the database, which look like the first two from the auction site.

Hi,

welcome to numista.

In my opinion, it's not even UNC.

Did you try to search for the coin in numista's database?

I did search the database, and it says this coin is uncirculating. I wondered why you would think it's not unc?

So this coin is just a satin finish? Since it looks like the satin finish  image in the database, that's why I doubt it's not a proof coin.

Maybe your coin has been in too much contact with some bad chemical air, since it's not shining at all and looks, imo, maximum AU.
