If his career weren't cut short due to injuries, Bo Jackson might have been the most electrifying athlete during the late 1980s and early 1990s. Bo Jackson was a unicorn - a true two-sport star and one of the greatest all-around athletes of all-time. With the exception of perhaps Deion Sanders, we haven't seen anything like him since he retired. And, unlike many of his contemporaries like Mark McGwire and Barry Bonds, Jackson was never tainted by the PED scandal that affected many of his peers.

Still, due to overproduction, many baseball and football cards during the late 1980s and early 1990s aren't worth that much, but key Bo Jackson cards are still popular collectibles. Here are some of his cards to consider collecting.

1987 Topps Future Stars #170

When Topps released its 1987 baseball cards, the sports card industry was booming. Due to heavy production, many of these cards lack value, but several cards are still highly sought after, especially if they're in high-grade. Bo Jackson's "future stars" card is one of those cards.

One of the few rookies in the set that lived up to the "future stars" branding, a PSA 10 copy of this card typically sells in the $150 range. A Topps Tiffany (glossier, lower production, higher grade card stock) version of this card might sell for closer to $500. In my opinion, the card doesn't have the best photograph of Jackson, which hurts its value.

A better Topps card, in my opinion, is his 1986 Topps Traded (#50T) card. Topps Traded is a set of cards that Topps published annually that features players who were either traded to a different team or made their debut during the regular season. A card with a clear headshot of Jackson, A PSA 10 copy of this card has sold in the $330 to $430 range in recent months on eBay.

1987 Donruss Bo Jackson Rated Rookie Card #35

In the early 1980s, Donruss entered the sports card business competing with Topps and Fleer. Like Topps and Fleer, Donruss also heavily printed its cards saturating the market. Still, like Jackson's 1987 card, this 1987 "rated rookie" card can still sell for a decent amount of money in high grade. A PSA 10 copy of this card will likely sell in the $125 to $150 range on eBay.

1988 Topps Football #327

This is one of Jackson's first and best football cards. A good photo of Jackson looking off into the distance and wearing the Raiders' silver and black, the card also has Topps's football's "super rookie" branding.

A PSA 10 copy of this card will cost you! During the past few months, PSA 10s have sold for around $1,500 on eBay. If you'd like a nice version of this card, there's a huge drop off in market value for a PSA 9. PSA 9s have sold in the $50 to $90 range on eBay.

1990 Score Bo Jackson #697

Score joined Topps, Fleer, and Donruss in 1988 adding to the glut of baseball cards flooding the market. Although Score wouldn't last long (Score produced its last set in 1998), they did produce this iconic Bo Jackson card that captures the essence of Jackson's popularity -- that he was a two-way star. Plus, the photo is similar to Upper Deck cards in terms of how it carefully considers the composition of the photograph and is framed horizontally instead of vertically.

Even though this card is easy to find, it still sells for a good amount of money in high grade. A PSA 10 copy of this card will likely sell in the $200 to $250 range on eBay.
