2015 Topps Heritage High Number Baseball takes the product back to a more traditional pack-based product. In recent years, it has been done as a premium-style factory set, first as an online exclusive then offered in hobby shops. Like the  main Heritage set that is also based on  1966 Topps, hobby boxes promise one autograph or relic card.

The 2015 Topps Heritage High Number Baseball base set has 225 cards. Similar to  Topps Update, it focuses on rookies and veterans who have found new homes. Numbering of the set continues on from the early-season release. The final 25 cards (#701-725) are short prints that land 1:3 packs. A total of 25 players have Action Variations that come with a different photo.

Collector s can also find Blue Back parallels. Fifty cards have Mini versions that are numbered to 100. Chrome cards, another partial parallel, return. In addition to basic versions, there are numbered Refractor, Black Refractor (#/66) and Gold Refractor (#/5) versions.

On the signature front, Real One Autographs are front and center. The checklist has a mix of current and retired players. Special Edition red ink versions return, numbered to 66 copies each. Real One Dual Autographs (#/25) have a pair of signatures. 1966 Cut Signatures (1/1) feature both baseball players and autographs of other figures who made an impact in the mid 1960s.

Clubhouse Collection Relics anchor the memorabilia portion of the release. Basic versions have Gold parallels numbered to 99. There are also Dual (#/66), Triple (#/25) and Quad (#/10) versions with multiple players. Clubhouse Collection Autographed Relics are numbered to 25 while Dual Autograph Relics are limited to ten copies each.

2015 Topps Heritage High Number Baseball has a few other basic inserts as well. Now and Then carries over from the main Heritage set, combining highlights from 2015 with similar achievements from 1966. Rookie Performers replaces New Age Performers with a focus on key 2015 first-year players. Award Winners note those who took home some major hardware in 2014.

Finally, there's Combos, which feature multiple players.

Hobby boxes come with a box loader. These can be Ad Panels, a strip of three cards, or a 1966 Topps Originals Buyback. These are cards from 1966 that have been given a foil stamp noting they've been reinserted in the product. 1966 Baseball Punchboards are the toughest of the box loaders to find. Basic versions are numbered to 50. There are also Jumbo Patch (#/25), Autograph (#/10) and Jumbo Patch Autographs (#/10).

24 packs per box, 9 cards per pack
