I don't know, I think we need the picture compressed and pixelated a little more before we can offer an informed opinion. Seriously, was that blown up from an eBay thumbnail, or what? I don't see how anyone can make a judgement about "square rims" or whatnot when each pixel is wider than the rim...
Well, there's one lie -- it's clearly lit from the upper right. It would be possible to downsample and compress a scan to be this lousy, but there's no way to make a scan look like it was lit from above like this. I don't see anything at all to make me trust the seller's claims.
Polished, polished, and... polished. At least they got portions of the coins in focus in some of the images, enough to see texture in the fields and hits on the devices that you wouldn't see on unimpaired proof coins. I could be wrong, of course, but it's hard for me to imagine how you'd make a proof coin look like that in a photo. I'm also distrustful of a new seller named "estateauctiondeals".
Impossible to tell from the photo (or on the other two coins on his site). But I don't care: brand new seller with bad photos. Enough for me right there. A decent '50 Franklin proof ain't cheap and the sheep may be being led to the slaughter.
No, you couldn't. Heavily buffed with a Dremel-size felt polishing wheel; you can see what they couldn't reach in some of the images.
