I’ll be honest—this is about the 3rd or 4th time I’ve tried to put together a guide on how to look up card values but each has missed the mark. The first post was detailed, but the next was even more specific, and the posts kept getting longer and longer, with more and more info.

But maybe I was making it too difficult? The process isn’t a complex one, so let’s scale things back. This post is still going because it has to be, but I’ve cut the fluff!

In short, the best way to find card values is to go to eBay and search for your card. You’ll want to check the current listings to understand how much you could sell the card for right now, along with the completed listings to see the amount the card has sold for recently.

1. Go to eBay.com

To get started, simply click this button to go to eBay. I’ve ensured the link opens in a new tab so you can still follow along.

2. Search for your card

Look at your card and search eBay for the main details. This includes the player’s name, card brand, card set, card year, card number, and any other specific details. Let’s do an example together.

2018 Topps Chrome - [Base] - Purple Refractor #100 - Mike Trout /299 - Courtesy of COMC.com

Looking at the front of this card, we see this is:

  • Player name: Mike Trout
  • Card Set: Topps Chrome
  • Card Year: TBD
  • Card Number: TBD
  • Specific Details: TBD

So far we know this is a Mike Trout card from Topps Chrome. It’s a good start, but if we were to search this card on eBay with these details, it would bring up many results, and most of which wouldn’t be this card.

Now, flip the card over and you’ll see this:

2018 Topps Chrome - [Base] - Purple Refractor #100 - Mike Trout /299 - Courtesy of COMC.com

Looking at the back of the card, we can fill out the rest:

  • Player name: Mike Trout
  • Card Set: Topps Chrome
  • Card Year: 2018
  • Card Number: 100

The last missing bit is “specific details” and I’ve left it blank because that could be a number of things, like:

  • Is the card autographed?
  • Does it contain a piece of the player’s uniform?
  • Is it a refractor or prizm?
  • Is the card serial numbered?
  • Is the card a variation of some sort?

In this case, the card is not autographed and it doesn’t not contain a uniform relic. We can’t be sure it’s a refractor, but it is serial numbered /299 (the first number isn’t as important, usually).

So with all of the above together, we know this is a 2018 Topps Chrome Mike Trout #100 /299. In most cases, this is enough information to look up the value of the card.

When we do, we see 7 card results!

3. Sort by lowest price

With 7 card results, we should now be able to find our card and its value. At this point, I like to search by the lowest price. (If you look at the photo above, you’ll see “Sort” and “Best Match.” Click that dropdown and select “Price + shipping lowest first.”

When doing so, we’ll see the 7 card prices as:

  • $55
  • $86.79
  • $99
  • $299.99
  • $325
  • $399.99
  • $850

As much as we’d love for our card to be worth $850, it’s not the case. You’ll notice the same of the cards listed on eBay are graded cards in slabs, and some are raw/ungraded.

Since we have an ungraded card, we want to make sure to only look at the raw card listings. When we sort by lowest price, it looks like the lowest-priced raw card like ours is $55. This tells me that if we were to list our card for sale, and we wanted it to sell quickly, we’d have to list it for less than $55.

At this point, your journey could end—you set out to look up the value of your card and you found it (about $55). But, what if we didn’t want to only know what the card is currently selling for, but what it sold for recently?

In that case, it might be good to look at the eBay sold listing data to see just how much this price has fluctuated over the past year.

4. Check completed listings

Before jumping in, let’s go back to the listings we just saw for sale on eBay. While we know the card is a 2018 Topps Chrome Mike Trout #100 /299, the listings tell us more: that this card is a refractor, and a purple one at that.

So now when we check the completed listings, we can add in this information to narow down the results. We can also use search operators like “-PSA” in order to filter out any graded cards.

To view completed listings, on the desktop, go to the filter on the left side of the screen and check the “Sold Items” box. On the mobile app, go to “filter” and then toggle the “Sold Items.”

When you do so, you’ll see a raw card like ours that sold for $39.99 plus shipping. Knowing that the card is currently listed at $55, this $39.99 sales price seems reasonable, and we can now put our card in the $40-$50 range.

Now, if we wanted, we could go a step further. Meaning, the data you see under the “sold items” filtering is data from the last 90 days. If you wanted to look even further back, you can use eBay’s price guide for 365-days of data. Simply click the “track the value of your…” button as shown here:

With all of that, is there more to know? There sure is. Sometimes simply finding the info to search for is hard enough. In most cases you shouldn’t have any problem finding the player’s name, set name, set year, and card number, but the specific beyond that could be tricky, and could end up being the different of a lot of money!

So, take your time—if you can’t find your exact card, that might be a good sign! Compare your card, front and back, to the cards listed. Remember “close enough” could severely overvalue or undervalue your card, so if you aren’t sure, ask and/or keep looking.
