So I decided to test out the new Coinsnap app grading feature to see how reliable it is. I tried it with a bunch of different coins and the results were not consistent with what I was seeing, then I decided to try the ultimate test. I snapped this extremely low grade 1919 Wheat cent and the app gave it a mint state grading. This confirms that the coinsnap app grading feature is seriously faulty and unreliable.    |

I think old school will remain for some time. Hard to beat a trained eye when grading. When in doubt, refer to the set of photos at the PCGS photo grade site.

Over time I feel those apps will become extremely useful once developed properly. Grading is simply too expensive for most coins to send in (at least moderns) and knowing a general range is helpful. So right now you'll have to continue posting on the forum to get opinions.
At this time many can help but seem to not work all that well. Coinoscope just should find a matching coin helping to id foreign coins for example but that rarely hits for me.

And how did it end up being a 1922, no D?

Such apps will soon be very accurate once the AI is refined. At least in the technical aspects. But will they ever be able to judge "eye appeal"?

Wow,
You can't more definitive than that.
App is not reliable.

maybe they'll not be able to judge eye appeal, only AI appeal
even humans can't judge fine grading details from a static photograph, for example, there is no substitute for being able to rotate and angle a coin to check its luster

I have been collecting coins for over forty years. I love CoinSnap and have graded 2000 of my coins with it. It is about 90% accurate. The two places where it has a problem is the one pointed out in this thread. Really bad coins are wildly mis-graded. The other place where grading does not work is where there is a brown stain on the coin. BTW, proper light is really important and can throw off the app. Once you discover how to properly light the coin it is very accurate.
One thing that I HATE is that when I export my library, it does not export the "Variety" which is where the mint stamp is stored. This makes it almost useless for keeping track of coins. (Use my own spreadsheet to track them).
Also, the pictures of the coins have to be exported one at a time.
Conclusion: Great for grading. Crap for keeping track of my coins.

Sometimes when its someones first post and in a first post endorses a product can be suspicious but its certainly possible the app has been improving as its paid so they can continue to invest money to improve the AI as time goes on. It is also possible as you say that certain types of coins such as very worn do worse than a typical low wear, AU or mint state coin that most would use it for so others may want to revisit it at some point to see for themselves and post their experiences. With the high cost of grading, even being within a few grades would at least help some people to know whether a coin is worth looking into further or not.

Well in fairness, the app does give the option of disagreeing with the findings on each coin.

this is wear newbies are getting these ridiculous prices. these apps are not ready for prime-time grading yet. maybe down the road. all they are doing now is either giving folks hope they found a mega coin or aid in someone getting ripped off paying those kinds of prices.
they don't help the coin collecting community at all
