Check value makes serious errors!

[EverLovinBlueEyedThing]

Guys, I’m a bit upset. I didn’t like that the subscription went up drastically this year but I stuck to it until I figure out if CLZ or Overstreet’s app works better.
I depend on these apps to help me to not only log my collection but to help me in making purchasing decisions.

I’ve been meaning to write that I’ve been noticing many times that CLZ’s Check Value feature does not give correct information.

I’ll give you a recent example.

Jan 11, 2026, Sunday, I saw All-New Venom #1J listed on ebay for $3.25 + $5.99 shipping. = $9.24

I checked CLZ’s Check Value feature and it was stating the value was $30+,

So I made the purchase thinking I’m getting a great deal.

I little while ago, I scanned it into CLZ and it’s stating that the value is only $9!!

I got upset because I remembered this happening to me before with your app.

I ran some tests right now and this is what I got;

Scan Test #1 a 7.5 grade is telling me the book is valued at $15.

Scan Test #2 a 9.9 grade is telling me the book is valued at $9.

Scan Test #3 a 7.0 grade is telling me the book is valued at $15.

Scan Test #4 a 4.0 grade is telling me the book is valued at $7.

Scan Test #5 a 1.0 grade is telling me the book is valued at $30.

Scan Test #6 a 0.1 grade, which is the worst grade is telling me the book is valued at $30!!

How can the value of this book be valued at $30. at 0.1 and $9. at 9.9??

Information like this is damaging to us. You cannot have your customers lose money making purchases with false and incorrect information like this.

Please fix this ASAP before someone loses a large amount of money, it’s a very serious problem with this app.

Here’s a copy of the screen captures;

First, I have moved your topic to the CovrPrice Values section.

Then, a quick tip: no need to do all these separate scans and screenshots. Just tap the “View on CovrPrice.com” link to see all values for all grades in one place:

That will immediately show you that only the NM+ value is a bit on the low side. AND it will also show you immediately WHY that is: the $28 value is based on a sale from almost a year ago (Feb ‘25).

All information you need is there for you, you just need to use the tools available to you.

Now, what is strange is that I see DIFFERENT values on the CP site. These do not match what you see in the app.
Let me look into this and see what is happening here.

In any case, it looks like you DID make a good deal buying this one, as an NM copy seems to be valued at $50

For most books, including moderns, it is very common to have limited sales data in the NM+ bucket. Most sellers don’t list books in such a way that promises a raw super high-grade copy, which means CovrPrice does not acquire a lot of sales data to populate the NM+ bucket.

As a reminder, CovrPrice reports the sales; we don’t manufacture values for grades for which we have no data or old data. Therefore, it’s good practice to click that View on CovrPrice.com link to get more context for a book’s value.

That being said, we are currently experiencing a site outage due to a widespread issue with a service provider…. So that link won’t help you at this very moment. Hopefully, the service provider will have things back up within minutes to hours….. We are all eagerly awaiting the end of this outage.

Hi Alwin,

I think I see what you’re saying. I clicked on the View on CP link and it brought me to a nice list of sales info, which I wasn’t aware of. At first I was curious why my purchase wasn’t listed but then when I scrolled down to “No Grade”, I saw a copy sold for $3.25 on Jan 11th. I’m guessing, that’s got to be my purchase. These numbers are coming from ebay right? And if they are, where else is the purchase data coming from? Etsy? Mile High Comics? Hip Comic? Midtown Comics? Heritage Auctions? Is there a list available?

Thanks for showing me where I can see in more detail what these books are / have been selling for.

There wasn’t any 9.9’s recorded on this CP chart, so why is it showing me on the CLZ app that a 9.9 is $9.00 when there’s no such information on the CP chart?

[MrDay-CP]

CP sales data sources include eBay, MCS, Heritage, ComicConnect and with more limited data from other sites like Hakes.

When CovrPrice does not have a value for a given grade, we give the Most Common Condition Fair Market Value (we don’t make up a predictive value based on a price curve). That is the FMV for the condition that has the most sales. If you have books that are of a grade way outside the norm, this can happen. 9.9’s for any book are pretty rare and its even more rare that there will be an open market sale for such a book. As such, you may want to use one of the value override options in either CP or CLZ’s solution where, based on other sales information, how much you paid, etc., you can enter your own value.

What is MCS?

Why are you saying 9.9’s are pretty rate when you can buy them new on release day?

[MrDay-CP]

MCS is mycomicshop.com. MCS sells thousands of comics every day and as such is one of the largest comic sellers out there.

While 9.9’s exist, they are not common and it is even less common to have actual sales data in any meaningful volume for 9.9 graded books. We have tens of millions of data points and only a tiny fraction of them are 9.9’s. On that book you were using as an example, All New Venom #1 Skan 1:25 edition, out of 70 total copies graded, there are zero 9.9’s on the CGC census and as such there can be no sales data for such a book. If sellers are promising 9.9’s at the time of release, they will not likely remain in business. 9.8’s for modern books are pretty common and there are often presales for 9.8’s, but 9.9’s and 10’s are a different story.

One additional point from your original message, I’m not sure how CLZ has any data for “.1” grades, but CovrPrice does not support that grade so any value info you’d get for selecting a .1 would likely be that most common condition fair market value (MCCFMV) and not a specific value for a .1 grade. MCCFMV is the fair market value for the grade bucket that has the most sales data points recorded.

It’s kind of crazy to believe that any new books published aren’t considered mint if they haven’t been graded by CGC yet.

[MrDay-CP]

Its not crazy if you look at the standards required for 9.9 or 10 (Mint and Gem Mint). The definition of a Gem Mint book is essentially a book of penultimate condition, and a 9.9 is one tiny step below that. Most books will never even have a book printed that meets the standard, even straight off the press. That’s because even minor printing irregularities that are allowed in a NM or even a 9.8 grade are not allowed at 9.9 or 10.

Generally those new release books are of a high grade (unless otherwise stated) - but its still not common for them to be guaranteed in the 9.6+ territory. That’s why we, by default, give every new release sold without a stated grade, a 9.2 up to a certain amount of time past the release date.
