Top 10 Kaboom! Sales of All-Time

Tom Brady just retired but he will likely be one of the most collectible athletes for a long time. He’s played in 10 Super Bowls, winning 7 of them, and set a bar so high that another Quarterback may not even come close to his accomplishments. 

2018 was the first year Kaboom! inserts were introduced into football products and it’s fitting that the pop 5 BGS 9.5 Brady insert holds the current record with a private sale of $120,000 on October 13th, 2021: 

What’s fascinating about this card is that a copy sold for $13,220 while Brady’s rookie cards were exploding in value, but it increased in value by over $100,000 within the following 8 months. 

In October 2021, this 1/1 Giannis Antetokounmpo 2018 Kaboom! Insert sold for $99,630: 

It’s the only recorded sale of the card and is the record for any basketball Kaboom! (so far). Giannis is an NBA Champion, 2x MPV, 6x All-Star, NBA defensive player of the year, and is a 3x All-NBA First Teamer. 

It’s likely that this record would be broken by a Lebron James Kaboom! Gold insert, but as it stands today, this Green 1/1 is the most expensive basketball Kaboom! insert sold.

At just 10 total copies, with 3 in a PSA 9 grade, the 2018 Tom Brady Kaboom! is the most valuable insert in football. A copy of this card sold in September 2021 for $80,000 via a private sale: 

Despite the news of Brady’s retirement, we haven’t seen a recent sale of his first-year Kaboom! gold featuring him in a Patriots uniform. This card is more valuable than a BGS 8.5 Brady 2000 Bowman Chrome Refractor Rookie (last sold for $72,000 on 1/23/22). 

Outside of Tom Brady, Mahomes is one of the most popular Quarterbacks that already has a Super Bowl Ring, MVP award, and two Super Bowl appearances under his belt by 26. 

Mahomes was a rookie in 2017, so his 2018 Kaboom! Gold Insert in a PSA 10 grade (pop 1) is the first year of this insert and it sold via private deal for $80,000: 

Mahomes' 2021-’22 season didn’t finish the way most of us thought it would, but in his 4 seasons as the Chief's primary starting QB, he’s already played in 2 Super Bowls and made it to the AFC Championship in the other 2 seasons. 

Justin Herbert took the NFL by storm during his rookie season, winning rookie of the year, but he is just 15–17 in his first two NFL seasons. Despite missing the playoffs this season, his on-field performance signals a bright future. 

Goldin Co. sold Herbert’s 1/1 Green Kaboom! PSA 9 for $79,200 making it the fifth-most expensive Kaboom! sold all-time. 

Steph Curry is a generational talent and was ranked the 13th-best NBA player of all time by ESPN. Curry is a 7-time NBA All-Star, 2-time MVP, 3-time NBA Champion, and now holds the NBA regular-season record for most three-pointers. 

His pop 4 PSA 10 Gold 2018 Kaboom! insert last sold for $66,000 on 2/19: 

The card sold for $1,927 less than two years earlier, which speaks to how much the demand for Kaboom! inserts have grown. 

There are 3 copies of Brady’s 2019 Absolute Kaboom! Gold in a BGS 9.5 grade and its record sale hit $70,000 via a private deal in September of 2021:

Given that football card products first launched Kabooms in 2018 and that Brady retired after the 2021 season, there are only 4 Kaboom! sets from his playing years (unless he comes back to play in the future). 

Brady frequents the #1 spot of NFL rankings and is largely considered one of the winningest athletes across any major sport. When you pair that with a limited supply of a popular insert from his playing years, you get eye-popping prices. 

Tom Brady shocked the world by leaving the New England Patriots to sign with the Tampa Bay Buccaneers, but he won a Super Bowl in his first year with the new team. 

Brady has two variations of his 2021 Absolute Kaboom! insert, one in a Bucs uniform and the other in a Patriots uniform. 

The former sold for $60,000 in a PSA 10 grade (pop 5) on 1/23/22: 

There are only 3 recorded sales of this card so far, with the record sale set on the first transaction. 

The Kaboom! insert wasn’t released during Mahomes’ rookie year, so 2018 and 2019 are the earliest you can get when it comes to these cards. 

There are 2 copies of Mahomes’ Gold Kaboom! insert in a BGS 10 grade with a copy selling for $49,200 in September 2021: 

The card sold for less than $15,000 just 4 months earlier despite being one of the most sought-after Quarterbacks in the hobby. 

Giannis rounds out our list as his 2018 Kaboom! PSA 10 Gold sold via GoldinCo for $46,800. There are multiple other 5-figure basketball Kaboom! sales including Kobe Bryant’s 2018 Panini Gold copy that sold for $33,000 in May 2021 and based on the growth of market popularity, they would likely sell for much higher today.
