I don't think so..... I don't know how you do that marking up thing on a photo...... If the photo were a clock face, look where 10:00 would be on the face.... Now that I see it, I can't see anything else!
Two ways I would use: cheek side down on the carpet, noting any irregular bumps or unexplained rises, or running your hands over the carpet, noting any movement of objects. Beyond that, I vote for the metal detector!
How far from top, side and bottom of photo? I download the photo, open the file, enlarge the pic. and edit the content.
No, I'm not. I can still do it. I said nothing about having to get up! That's when I call the wife! (And hope she gets there before the dog licks me to death!)
Maybe @JayAg47 will verify my post or show us where the coin is, probably tomorrow because he lives in Australia.
