Nate's got it right, it might even be easier.
Those two scans aren't looking good.
But before we get out the pitchforks I'd like to be certain of one thing.
That the dot is actually on the card, and not "stuff" on the scanner glass or slab.
I regularly have to clean my scanner. I usually find "stuff" on there after I do a scan and see something I didn't think was on the card. I have a 3 year old, one card developed a nice yellow smiley face - Fortunately it was only drawn on the scanner glass. The gooey cheerio on the other hand became a feature of a cheap 80's common, which was added to the scanner by her. At least she's showing some interest.
So it's not impossible for stuff to get on the scanner. (I'm seeing the red dot as a result of scanning during lunch, perhaps a hot dog with ketchup?)
Or the scan has been played with. Removing something like that is beyond what I'd consider ok.
Any chance the person with the info was the first buyer? That would clear it right up. Or if someone knows the current owner or consigner.
