After winning his first NBA championship with the Milwaukee Bucks a couple of months ago, Giannis Antetokounmpo is definitely on top of the world. Right after the NBA Finals, the two-time MVP was seen appearing at an AEW match, strolling the streets of Greece with the championship trophy, and just having the time of his life in general with family, among other things.

But even after winning it all, there are still some things that make The Greek Freak yellow with envy. One good example is this monster 1-of-1 basketball card that caught Antetokounmpo's attention:

Over on Twitter, the Bucks star retweeted a collector's sweet pull of him: a PSA 10 2017 Panini Prizm Mosaic Black 1-of-1. The pair of photos showcase the slab in all of its majestic glory, with The Greek Freak front and center. And since this is the only one of its kind in existence, there's reason enough for Antetokoumpo to want this insane graded card.

The Bucks' All-Star forward is no stranger when it comes to collecting sports cards. He himself has amassed quite the collection of NBA cards, which are mostly of him. In a video he shared on TikTok and deleted right after, Antetokounmpo showcased an impressive array of cards worth a lot of money:

Even his brother, Thanasis, has a collection of Giannis Antetokoumpo cards that would fill any collector with envy.

Now that The Greek Freak has won the championship and Finals MVP this year with the Bucks, there's not a lot he can do. Whether he makes an offer that can't be refused or not remains to be seen. What's certain is that Antetokoumpo will continue collecting his cards, especially those that hold a lot of value on the market.
