2015 Topps Tier One Baseball is one of those products you're rolling the dice with. The all-hits configuration means plenty of autographs and memorabilia cards but no base cards. While that probably means that it's not for some collectors, it's a reason why many others collect today.
Boxes have just three cards: two autographs and one relic. Like most products with similar configurations, there's a mix of key players and other youngsters that will likely cause more head shakes and questions about why they're in a pricey product like this. But that's the nature of high-end products.
2015 Topps Tier One Baseball does have its share of premium rarities. The brand has done a good job in its short history to carve out a niche as being a destination for bat knobs. While the unique end pieces can be found in other products, the checklists in Tier One have been big. It started out with basic bat knobs before making the natural extension to autographed versions. This year, things go a step further and slide down the bat with Limited Lumber. These go to other premium parts of the bat with logos and parts where colors split.
Prodigious Patches is another part of the Tier One brand. These come with over-sized swatches that take up the majority of the card front. While these are rare to begin with, there are even tougher autographed versions as well that are even tougher.
For autograph collectors, the vast majority of the signatures in the product are on-card. Signers are a broad mix of veterans, young players and retired players. Top names include Ken Griffey Jr, Bryce Harper, Mike Trout, Hank Aaron and Sandy Koufax. Oh, yeah -- and Kris Bryant (as a redemption).
