The 1983 Topps baseball card set is one of my favorites of the 1980s for three reasons:

• the design is fantastic (with a nod to the 1963 set design)
• its loaded with stars and Hall of Famers
• it contains three key Hall of Fame rookie cards in Tony Gwynn, Wade Boggs and Ryne Sandberg

As Fleer and Donruss had entered the market a couple years earlier, you could clearly see that Topps was trying to step up its game to hold off its competitors.

There’s just so much to love about this set as it was one of the last sets produced before the “Junk Era” was underway later that decade.

And in this guide, I’ll run through the ten most valuable to look for.

Let’s jump right in!

While 1990 Fleer basketball cards have not held up as well over time as some of the other Fleer sets, they do remain some of the most recognizable basketball cards of the “junk era”.

For years during the 1980s, there were hardly any basketball cards to collect whatsoever…

Topps bowed out of the hobby after 1981, Star released a few sets later on and Fleer didn’t join the market until 1986.

However, by 1990, the basketball card hobby was clearly back on the map as kids everywhere were ripping through packs in hopes of pulling a Michael Jordan.

What this set may lack in terms of overall value, it certainly makes up in nostalgia.

And in this guide, we look at the 11 most valuable the set has to offer.

Let’s get started!

I’ve always thought that 1990 Upper Deck baseball cards have been somewhat overlooked in the hobby…

True, the set is lacking of any iconic rookie cards.

And most of the cards in the set have long since seen their values plummet.

But, the set did feature fantastic photography, some interesting errors/variations, and most significantly, the first pack-inserted cards with a player’s autograph (Reggie Jackson) on them.

Those autograph inserts forever changed the hobby as most every set produced these days contains autograph inserts.

But do any of the other cards in this hobby-changing set really have much value these days?

In this guide, I’ll take a look at the 10 most valuable and some of their values may surprise you.

Let’s jump right in!

I will always remember the 1991 Fleer baseball card set for one simple reason:

it was the first factory set I ever owned.

My grandpa purchased the factory set at a flea market one year and gave it to me as a birthday present.

To this day, I still have it in my possession…

While monetarily it’s not worth anymore today than when he bought it all those years ago, it will always fill me with nostalgia and fantastic memories of my grandpa and early collecting days.

In all, the 1991 Fleer set wasn’t well-received by collectors as it lacked star rookie power and its design was considered to be underwhelming.

Regardless, in this guide, I’ll run through the 10 most valuable to look for.
