High grading and valuation issues

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.

Inaccurate

Told coins had significant value. They do not according to a reputable local coin appraiser.

Not accurate

Does not pick up privy mark.

First time user

Very easy to find the value of coins. Estimated value is spot on. Easy to use and thus far, no cost. You can go pro for a fee.

Scam

Constantly wrong dates and identifications. Never finds errors.

Syncing phones

The app is good, but when I tried to sync the apps on mine and my boyfriends phones, it deleted his collections.

To many review requests interrupting constantly

Annoying

Great concept but inconsistent

Every photo of the same coin gets me a different answer. One was $350 another response of the same coin was $4 so??

Kept giving the same response

Every time I checked a penny especially one in decent shape- it gives the correct response- but when I would do the back of the coin every response was that the coin was a “ wheatie” from the early 1900’s. Had the same issue with Roosevelt dimes.

I mean it is a joke it didn’t work at all

This app did not work even a little bit it didn’t scan a single coin correctly and it costs money to scan them

Camera doesn’t take pictures well.

Haven’t gotten to get a good picture . Then , you’re wanting more money for a different membership that was never explained really !

Not worth paying for

Needs improvement

Waste of my money

Wish I hadn't purchased Just a waste of my money another thing that takes your money and no response or no difference from the free app

Serious collectors- AVOID

The software is at best a late alpha version. Many inconsistencies. Shows mint when identifying, but later panels show mint as N/A. Misidentification of American Women quarters. Still doesn’t have 2026 coins at end of April. Often shows previously scanned coin image for new coins. Or shows a placeholder when an image was there et scan time! Devs need better QA and more resources.

Review

Easy to use. Fun.

Wrong Information and Value Amount.

I don’t know who rated this app with four stars. The only things this app does correctly is snap a photo (not a good one at that) and charge you for the subscription.
Anyone opting to use this app with a subscription, beware. Those who have left a rating over one star is either paid to do so or is delusional. To the app maker,
Don’t bother responding with an excuse. Because I didn’t pay for it. If I had, that would be a different story.

Coinknow is bad

Every coin I scanned it would tell me what it was but to get value it stated it wasn’t in data base

My Opinion

So so good
