Is it just me?

I recently purchased this Proof 1954 Roosevelt on Ebay. I was busy when it arrived, so I gave it the once over and put it aside.(Dummy) Upon closer inspection it seems apparent(to me) that the slab was opened and the coin switched and the slab was remelted back together. If you'll notice the cloudy/(obviously melted) area at 6 and 9 o'clock on the obverse shot, there's a smaller melted area at 3 o'clock that does'nt show in the scan.

Am I right or am I worrying about nothing? All my other NGC coins have a smooth outer edge where they are sealed shut, this one has 3 areas that are'nt(look melted). I entered the coin in my registry set and the number checks out OK. So I believe the slab is legit, but the coin looks pretty rough for a Proof 67 to me.

Thanks for any info everybody can give me!
