Which tool for figuring out the value of my collection?

Because I am writing a story about “my road to a million” I have to figure out how much my collection is worth.
Started in 2021 and decided to write about the missing years up to today.

The PSA register is not accurate at all.
I do have 2 apps on my phone, Collectr and Cardladder. But which one is the most acurate one?
I will only count my PSA graded collection.

It’s going to be very time consuming job to put all cards (around 2500 at this moment) in any of those, but I need to figure out the value.
I like to read some opinions.

There will always be some inaccuracy because of the way these apps pull in last sold data. Seems worth it for the convenience of not having to track it in your spreadsheet though. Fanatics and PSA refer to card ladder values

I check collectr but just assume whatever it shows there needs a 20-30% cut from shipping/fees/negotiation + an additional uncertainty since most if it is raw

Yeah I guess it depends on the accuracy you’d be happy with vs the effort involved. If you want to do it more accurately, if you know someone good with Excel (or perhaps AI could do it now?) you could potentially create a spreadsheet that pulled the several most recent sold prices from eBay for a given search term in a given date range and take the average result for each. Regardless of which method you use the nature of card sales means there can always be 10, 20 or even 30% swings in value between any two sales of the same item even within short timeframes so it may just be that you have to accept there will always be a certain margin for error along the way.

I don’t care if there is a minus 20% from the total I get out of these apps.
I was never interested in the grand total and untill today I’m not really.
However writing om my road to a million I need to check, there has been so much increase of value…
But I am almost sure there is at least a 50% difference in the value the PSA set register shows and any of those apps.

Some cards don’t even show up with a value in the PSA register.

Collectr seems the have the best options, I like it you can create several portfolio’s.

Collectr also has a scan function to identify and upload cards. This can shorten the time entering cards.

Others like TCG have this but it is more glitchy

If you’re not all that bothered for tracking with as much accuracy as possible, then +1 for just sticking with Collectr. The database is lacking in some areas, and pricing can be inaccurate but it’s slick and hard to beat for what it does.

Is accuracy possible? I don’t think you can keep up with that with a large collection.
It’s about estimates.
For me indeed it’s not important, my collection is not about the value, never been.
But because I’m into this from the start (around 2000) I have seen prices go up than going down down down down till the point nobody was interested in them, going up en down, up, up down. (well you get the point).
In general my collection is way more worth as the moment I pulled the cards from their boosters or won at tournaments.
But there is no solid value it’s always an estimate.

So yes I don’t have a problem with a 30% lower “value” as what I will find at the end.
For me it’s easy, it’s without a doubt worth so much more.
Few weeks ago somebody told me to get collectr and I did put a few cards in it so see how it worked. Almost got a heartattack after seeing those values.
Closed it and didn’t want to look at it.

When your collection you worked on with so much pleasure turns into a very valuable possession, somehow the pleasure disappears partly. NO more careless displaying your items in your living room, but renting vaults to store it being afraid it get stolen.

So this year forced me to rethink my goals and that’s why I’m writing a follow up in the millionaire topic.

Well now I’m confused because in your OP you said:

Which implies you were looking for more accuracy, hence the excel/ebay sold tracking suggestion.

The title of this thread is literally “which tool for figuring out the value of my collection?” And the entire premise of your last thread is that you’re trying to reach ‘a million.’

Hmm

PSA register is simply not counting half of the cards in my collection. While I am not seeking to find exactly the value it’s nice if I would know if part x of my collection is worth 1k of 30k or 100k iso fo 10k
While I don’t have to know if a certain card is worth 200 or 220 dollar Or perhaps 1000 or 1100. The way PSA register is so far way off I need to figure out what is a bit more acurate. That’s why I am trying to get a global insight on the “about” value.
According to the PSA register for example my reverse Skyridge set is worth TODAY $12,663.11.

So I did put half of it in Collectr TODAY and after adding 59 cards it’s already on 74,011.48
The difference is huge.

Yes 5 years ago I thought my graded collection could be worth around a million after selling the main part of it and going forward with the “left overs”.
I joked around about it, because at that time I didn’t think it wasn’t going to be there, but you can hope.

There was a time when I used to audit my collection in its entirety on an annual basis. I used https://130point.com to look up prices for every card, or at least those that were above a certain price point. The rest, I could guess their value given prices that I paid and adding some arbitrary market percentage.

It’s been much more difficult to do this as the market prices seem to change daily in 2026. But if you have a favorite movie or TV show, you can waste some hours doing it the old-fashioned way. It will be the most accurate, but also the most amount of work.

From what it sounds like, Collectr does this for you and it updates automatically. I haven’t tried it, but I would consider it in the future. Manual accounting is too cumbersome in the age of AI and apps. Hope this helps!

Cardladder generates price estimates based on a combination of last sold prices + speculation if last sold is not recent. There are collection trackers that have commercial subscriptions to cardladder and will show you the cardladder estimate for items in your collection

Vendor bro app but I think of it as 130point automation

from my experience this is also glitchy in collectr and not a reliable way to save time adding cards unless maybe you hit the sweet spot of common enough unique artwork that the machine vision understands more easily
