CoinKnow: Coin Identifier

Such a great concept, but improvements are needed. In general, I found grading is too high. Lighting plays such a key role. I’ve tried emailing support but never get a response at least yet. The valuation does not seem to be consistent between grades for the same coin. Lighting is not a factor on this particular issue. For example, a 1944S Lincoln penny is valued at $17 in VG (8) condition and $1 in F(12) condition. Another example would be a 1955-D Lincoln penny in VF condition you value at $330 when it’s really only worth about $0.25. I wonder how many high valuations I have wrong because I didn’t double check the value generated by your app against an AI tool. Additionally, if you scan a US two cent and three cent piece, in both cases, it returns with no space between two cent and three cent names. So it can’t find the coin. If you manually add a space (twocents vs two cents), it finds the coin category, but you’ve lost the photo and all the relevant details from the prior scan. Finally, you really need to add search criteria and filter criteria to the collection you allow people to build. There is no easy or good way to find a specific coin without manually going through each coin you have scanned into the collection. That frankly is not usable.

Just downloaded the CoinKnow app and tried it out. Took pictures of 6 coins, then canceled the “free subscription”. The following list is in order of my personal frustration attempting to use the app. 1) the camera is awful. It doesn’t zoom automatically, and efforts to make not blurry or enlarge are futile. In addition, there’s a misleading message above the frame telling the user to center the coin within the frame. Naturally, the user then spends an exorbitant amount of time trying to get the picture just right until it becomes obvious the message doesn’t ever go away. 2) since I didn’t save my first coin to a collection, and I was given a value of over $30, I searched for it in the history, but it was nowhere to be found. I took a second picture, and then was given a value of $2.00. 3) I downloaded the app because it’s advertised as detecting irregularities. However, in the description of each coin, there wasn’t any mention of irregularities. I believe, at the very least, the app should provide what errors have been found on that coin, and if any of them were detected on this one. 4) when finished with the specific coin, to go back to the main menu to capture a new coin, the user has to manually scroll back to the top and select the back arrow more than once. The app would be improved if rather than manually going all the way back to the main menus, an obvious user button was added for “new coin”. My time is too valuable to consider this app. Thank you,

All around this app is the best just one minor thing is the zooming in and out could be better navigation wise because it’s hard to get a good position for capturing the image
