The 2015 baseball season is underway, and that means it’s time for collectors to start scouting the best baseball cards to add to their collections for the coming year. With rookies like Kris Bryant and Carlos Correa making their debuts, and stars like Mike Trout and Clayton Kershaw continuing their dominance on the field, there are plenty of exciting cards hitting the market. Here’s a look at some of the top options collectors should consider in 2015:

2015 Topps Series 1: The flagship Topps set is always a great starting point, and the 2015 edition features many of the game’s biggest names and prospects. Look for short prints and parallels of stars like Trout, Kershaw, and Bryce Harper. Top rookies to watch include Bryant, Correa, and Noah Syndergaard. A Bryant or Correa rookie could be one of the best long-term investments of the year.

2015 Bowman Baseball: Much like Topps Series 1, Bowman is a premier release that highlights top talents. The photography and design tends to be sharper than Topps as well. Top rookies to target include shortstop Corey Seager, outfielder Joc Pederson, and pitchers Tyler Glasnow and Julio Urias. Parallels and autographs of any of these young stars could pay off down the road.

2015 Stadium Club: Stadium Club is known for its elegant photography, and the 2015 edition continues that tradition. The set stands out from the crowd with its crisp images on high-quality card stock. Trout and Kershaw are always highlights, but look also for rookie cards of top prospects like Francisco Lindor, Addison Russell, and Joey Gallo. Autographs and memorabilia cards are also coveted inserts.

2015 Topps Chrome: The refractor parallel of Topps Series 1 is a must-have for collectors wanting the shiniest versions of stars. Trout, Harper, and others truly pop in the Chrome format. The design is clean and classic, making for cards that will retain value. Short prints, autographs, and numbered parallels are keys to finding the set’s big hits.

2015 Tier One Baseball: Upper deck’s high-end release always features some of the most exquisite photography and printing quality in the hobby. Rated rookies of top talents like Bryant, Pederson, and Aaron Nola are highlights. But the real chase is parallel autographs of the game’s elite, including Trout, Kershaw, and Andrew McCutchen. With only 100 copies made, these autographs are true collector’s items.

2015 Triple Threads: The pinnacle of on-card relic and autograph cards. Triple Threads features swatches of game-used jerseys, hats or pants alongside autographs. Finding a 1/1 triple relic autograph of a star is the ultimate prize. Trout, Harper and others command huge prices in this exclusive format. Even base relic cards of top talents can hold value long-term.

2015 Panini Prizm Baseball: Panini’s flashy Prizm set uses prismatic foil technology to make players truly pop on the card. Rookie cards of top prospects like Correa, Syndergaard and Steven Matz are standouts. Autographs and memorabilia cards of young stars could be some of the best modern investments of the year. The design and parallels make for flashy cards that collectors love.

2015 Topps Finest Baseball: Topps Finest features some of the sharpest photography in the industry alongside high-end parallels and autographs. Short prints of big names are popular chase cards. But rookie autographs of budding talents like Bryant, Pederson and Seager could be long-term keys to the set. The silky card stock and clean design make Finest a premier modern issue.

While those sets highlight some of the biggest releases, savvy collectors will also want to scout regional and retail exclusives issued by brands like Leaf, Donruss, and Panini. Rookie cards of breakout talents from sets like Donruss Optic, Leaf Metal Draft, and Bowman Sterling are always worth tracking down. And don’t forget vintage! Stars of the past like Mickey Mantle, Willie Mays and Hank Aaron remain popular, and high-grade vintage can earn strong returns. Whether chasing new stars or timeless classics, 2015 offers no shortage of great cardboard to add to any collection. With rookies like Bryant and Correa poised to become the next generation of MLB greats, their earliest cards could prove to be brilliant long-term investments.
