Heat damaged WTC 9/11 recovery Silver Eagle

Happened across this Silver Eagle with what appears to be some sort of discolouration. Wondered whether if is one of the heat damaged examples?

 

 

“The 2001 silver eagle BU PCGS certified coin was the most common coin found at the vault under the world trade center. It took months to retrieve the coins from the sub-basement where the vault with these coins where located. Some special WTC 2001 Coin to look for would be coins found to display heat marks making the coin black in spots. These coins are often referred as "end roll coins" because they where the last or first coin in a role and these coins would have absorbed most of the destructive power of the falling buildings and the fire that burned at the world trade center.”

 

Would like to hear other collectors opinions.
 

Has anyone got a confirmed heat damaged one, we could compare this with?

Not sure whether the previous example is heat damage or just some sort of discolouration?

But this one looks pretty convincing!!
