For this kind of AI, no, they actually aren't. They're developed by training, or by selection. Saying that the resulting algorithms (actually...
That answered my first question. :) I don't see any obvious signs of harsh cleaning or wear, although it's still a bit hard to tell from the...
Needs to be straight-on so the entire coin is in focus, and it might help to have different light. From this shot, I can't tell whether it's been...
That won't help if the digicam can't focus any closer. @RabidRick, does your camera have a "Macro" setting? If not, can you crop the photo down...
Wow. Is that spattered, chaotic toning really considered "desirable"? If I came across toning like this on an "ordinary mortal's" coin, I...
Looks like he's been trying to move these for a while. Guess there aren't that many people willing to pay a big premium for a common-date example...
I understand your view. Most people, maybe even most AI practitioners, would agree with it. Me, I'm not so sure. I'm starting to think that...
Many (most?) scanners will only produce a sharp image of something that's flat against the glass. The coin's surface is at least a millimeter or...

Both ignorant and knowledgeable people can put on a dialect for effect. I find it a bit annoying, but I've had to learn to put up with all sorts...

You're not the only one waiting until the last few seconds to bid. Sometimes, you're the high bidder; sometimes, someone else is. More than one...
Wow, it looks like it's coming out in flakes -- that's not what I would've expected. Looking forward to the photos from the next steps! If you're...
That was my first thought, too, but I see a lot more luster than I'm used to seeing on XF coins. Then again, I haven't seen that many XF V's in-hand.
And on the other hand, you don't want passing kids or dogs to not realize that it's full of toxic and corrosive liquid and gas, and give it a big...
Sounds like a job for an automated system. ;) Yes, I know that computer grading was tried and failed in the past. I imagine part of the reason...
I tackled more dangerous processes than that as a chemistry hobbyist, but I didn't have the stomach for it once I was paying my own homeowner's...
The idea that I could flip the sets for a $20 profit makes me wish I'd ordered the full 5 instead of just 2. I have to think, though, that that...
Separate names with a comma.
