Possible Error, Opinions Needed 0

[THENUMISMASTER]

Hello all!  I'm new to the site, but not new to numismatics.  I recently joined the ANA's YN program, and was able to redeem a free membership with the NGC. A friend recently found this coin in circulation, and has some questions that I cannot answer, and thought I would ask all of you.  This 1999 penny appears to be double-stuck, and also looks like it was flipped over for one of the strikes.  Its difficult to see in the picture, but you can see some of lincoln on the reverse, and can clearly see it say "UNITED" right below lincoln on the obverse.  In the 5th picture I have included, you can see a second rim from one of the strikes.  

His question was first off, what exactly IS this error, what do you think it is worth, and if he were to send it in to NGC, what grade do you think it would receive, and what would the value be?  Would sending it to NCS help?  Thank you for helping us out!
Cheers, NM

Also worth noting that the "United" and memorial on lincoln's body are intended rather than raised, so my thoughts are that maybe another penny was sitting below it when it was struck the second time.

Looks like a vise job, another coin was squeezed into it in a vise or hit with a hammer.  Just damage. Keep looking and studying, coin collecting is a great hobby!

From the photos my thought is vice job, lets see if anyone has other thoughts on this.

But how does that explain the second rim?  That is a raised line, not an indentation.

Hi, although it may not look like it, I am sorry to say the second rim is actually indented to the coin.

I have to agree also. Looks like a vice job to me. If it had been double struck, the lettering would be the correct way instead of backwards.

 I believe the rim of the other coin pushed up a ridge of displaced metal when it was pressed in.

It's a damaged coin and does not represent a mint error.

There it is.  (I was already thinking proper burial but that is no way to greet a guest looking for some honest answers.)
