Hi, just joined and doing some reading to learn about the hobby. I have a collection inherited from a grandfather who collected from spare change in the 40s - 80s... I have reviewed a lot of the collection (maybe 3000 coins?) but would like to start looking at my OWN change using an app for quick review. I'm not interested in grading with the app, more to identify a special coin that would go unnoticed... ie, its great that I have a 1956 nickel, but can any app look at that nickel and spike out anything special about it vs just a standard nickel? I tried CoinSnap and it identified a ton of coins and then game me INFO about possible errors and special"ness" but it didn't identify it on MY coin - so then I would have to review the coin related to these marks on my own. That is fine - just curious if there is another tool that can help the process since I do have a lot of existing coins to review in additional to any new coins I find. Thoughts? Thanks! steve |

 There is really no short cut in the hobby. Reasearch is the key. John1

Thanks, yeah that makes sense. I'm not sure the value of these apps since they seem to just tell me what I already know... it is a XXXX year nickel... yeah, I know that. Didn't know if there were any apps that had better AI to notice if the coin was special in some way.
But, I'll keep learning more about what to look for

One thing you can do is use the PCGS site. Not just for its photograde but also to view the different varieties of any particular date and denomination. Go to the PCGS site. From the toolbar at the top of the page click price guide. From there you can chose your denomination. Then you can choose the specific date in question by clicking the number to the left of the selected date and a picture of that coin will appear. Scroll down the page below the picture to click "Show Related Varieties".

I think we're still a long ways from an app that would recognize varieties. Things like differentiating MD and DDD from true doubling seems like would be very difficult to automate. Same with minor design varieties. |

Great question you would kind of think that by now with the advancement of AI, that it could figure , Through clear photos, if a Coin has any errors or distinguish between varieties, which would be helpful in a huge way to people who are new at for people who just don't have the time for other people ask myself who is legally blind, and other such, having In common and love For numismatics Period heck, ai can do just about everything else, Or use AI technology to create a phone camera that can actually take close-up photos, quality close-up photos

There are none. I highly doubt there will be in our lifetimes. Just take a few days to study the minting process.

All errors are unique so I'd imagine it would be extremely difficult to have a robot assess a genuine mint error accurately. We have plenty of well versed error experts here on the forum that are happy to help.

Image analysis software has exited for decades. It's used in the lab to count things, size things, run statistics on features in electron micrographs, etc. I'm sure that 5 or 10 generations later it is even more powerful than the first time I encountered it.
I imagine it would be very simple to program a piece of software for "normal" versions (and ranges) of designs, dates, mint marks, etc., then let it pick out the flyers. Just takes someone with the right combination of numismatic and tech skills.

Seems to me that an accurate dynamic data base would be the key.
The highest rated coins would be the standard.
Is a coin minted like this yes or no?

The local radiographer says that most hospitals use AI to spot abnormalities. She says that some scans are definites and a doctor checks them and almost always arranges a follow-up, some scans AI isn't sure about and a doctor checks them. They used to check all the negatives but now only check a random sample, because when they were checking negatives, doctors confirmed they were all negative. I discussed the coin problem with her. She thinks it would be important for photos of all coins to be done at the same resolution as the reference photos. Apparently what's important is to have lots of samples of the same error; the AI needs to be trained - the more reference photos, the more accurate are the results. She doesn't think it would matter if test coins are slightly rotated from the reference photo. She expects that AI would detect some but not errors, some it wouldn't be sure about, and some would be rejected.
