The collector's take on Kieran

Is Kieran worth grading?

So is Kieran worth grading? Let's talk it through honestly. A raw copy runs $28, but a PSA 10 is worth $718, which works out to about 25.7 times the raw price. That's a serious jump, and it's exactly why people send copies in. But here's the catch: hitting a true gem mint PSA 10 isn't easy, corners, centering, and surface all have to cooperate, and plenty of nice-looking copies come back as a Grade 9 instead. Grading costs money and time, and there's no guarantee your card comes back at the top. If your copy looks clean under a light with sharp corners and solid centering, it's worth the gamble. If it's got soft edges or a whitened corner, save yourself the fee and enjoy it raw.

How rare is Kieran?

Right now there are 1,958 graded copies of Kieran on record, and of those, 840 have earned a PSA 10. That's actually a fairly high proportion making the top grade compared to a lot of cards out there, which tells you this one isn't impossible to find in gem mint condition, just not guaranteed either. Scarcity like this matters because it sets the ceiling: with a defined population and a meaningful chunk sitting at PSA 10, the price gap between raw and graded holds steady rather than swinging wildly.

Where can you pull Kieran?

This is where PackSpy's own tracking comes in, since we record real pulls across pack-opening sites, not just price guide estimates. Kieran has been pulled 200 or more times across tilt-rips, courtyard, collector-crypt, and mnstr, so it's a card that does show up if you're opening from the right products. We've seen it land in the Novice Pack, Pokemon Mini Pack, Rookie Pack, Pokemon Dime Pack, and Pokemon Expert Pack, with the biggest recorded pull value on our books at $100. Worth remembering, though: opening packs is gambling, and most rips don't come close to covering what you paid. If you're chasing this card specifically, buying a known copy on the secondary market is often the steadier route, but if you love the thrill of the pull, these are the products where it's actually been showing up.

Questions people ask

How much is Kieran worth?+

A raw, ungraded copy of Kieran is valued at $28. That's the baseline most collectors reference before factoring in grading, since a strong PSA 10 or even a Grade 9 changes the number substantially.

Is Kieran worth grading?+

It can be, since a PSA 10 is worth 25.7 times the raw price. But grading costs money, takes time, and there's no guarantee of a top grade, so it really comes down to how clean your specific copy looks before you send it in.

How much is a PSA 10 Kieran worth?+

A PSA 10 Kieran is valued at $718, a big step up from the $28 raw price. Interestingly, a Grade 9 currently sits even higher at $896, so it's worth checking current values for both grades before deciding what to aim for.
