If there were ever a set that made you wish you had a time machine, 1986 Fleer basketball cards would certainly be one of them.

Just look at how far prices of some of these cards have skyrocketed over the years...

Many of these cards have gone up nearly ten-fold over the last ten years alone.

But, back in the 80s and early 90s, hobby shops struggled to sell them and they could be found dirt cheap

Funny how things can swing drastically in this hobby over time.

Since then, many of these guys turned into Hall of Famers, The Last Dance on ESPN fueled collector interest in basketball cards, and the hobby as a whole has been on an uptick as of late.

Most importantly, Michael Jordan's transformation into a basketball and cultural icon has sent his rookie card prices to meteoric heights.

As they say, a rising tide lifts all boats.

So just how expensive are some of these cards?

In this guide, I run through the fifteen most valuable.

Let's jump right in!

Few sets in this hobby resonate as universally well among collectors as the 1953 Topps baseball cards do.

And it has everything to do with what many consider to be the most beautiful artwork ever to grace the fronts of any baseball card set...

While its 274-card checklist may pale in size compared to its 407-card predecessor, the legendary 1952 Topps set, many would argue that these cards pack more aesthetic punch than any other hobby history.

Single prints, double prints, out-of-order printing sequences, and outright omissions of certain cards may have initially created confusion among collectors.

But, evidently, hobbyists have long since gotten over the puzzling printing process and cherish these cards.

And in this guide, I'll run through the twelve most valuable.

Initially released in Japan in the 1990s to accompany the Pokémon video games, the Pokémon Trading Card Game has transformed into one of the most popular trading card games of all-time.

Because of the red-hot popularity of the franchise, some of the most expensive Pokemon cards can sell into the six-figure range and beyond...

That may sound shocking, at first, but given that Pokémon is a worldwide phenom, there is a vast, passionate collector base around the globe just waiting to get their hands on these prized cards.

From trophy cards, to First Edition Pokemon cards, to lesser-known rarities, the value of these cards is quite impressive.

And in this guide, we take a look at the 25 most valuable Pokemon cards ever sold.

Of all the great baseball cards made during the 1970s, the Mike Schmidt rookie card certainly stands out as one of the decade's best.

It's not entirely his rookie card all to himself, though...

Ron Cey and John (Dave) Hilton also share in the spotlight of this hobby favorite.

The 1973 Topps set itself has never been one of my personal favorites but I have always been a huge fan of the Schmidt rookie.

How could you not be?

He was simply one of the best, if not the best, third baseman ever to play the game...

And this guide I go over everything you need to know about collecting his rookie cards.
