The 1970 Topps High Number Series and Its Demanding Final Stretch
The 1970 Topps baseball set has long been a fixture in card collections, but its final stretch is famously unforgiving. While the early and middle series card counts flowed through candy racks and corner shops across North America without much fuss, the cards numbered 634 through 720 turned into something of a scavenger hunt. Collectors who managed to complete the run often speak of those high number cards with the sort of reverence usually reserved for vintage rookie cards.
In Australia, that scavenger hunt carries extra weight. A run of 1970 Topps high numbers tends to surface in Melbourne hobby stores, Sydney weekend markets and the occasional Adelaide estate sale, but never in great quantity. Distance from the United States, where most surviving inventory is held, means that sourcing these cards usually involves long shipping windows, currency conversion from AUD to USD, and a fair amount of patience waiting for parcels routed through Australia Post.
The high number series grew notorious for a handful of reasons that still frustrate set builders today. Print totals for those final cards were lower, centering was inconsistent across the run, and corner wear seemed baked into the manufacturing process. Even cards that look stunning in catalog scans often turn up with soft edges, gum stains along the borders, or registration drift that pulls the design slightly off centre.
This piece walks through the history of those final 87 cards, profiles the names that collectors chase hardest, and offers a few practical notes for finishing the set from an Australian base. A short comparison of how the three series of the 1970 issue differ in availability and condition expectations sits in the section below.
Series structure and how the high numbers came to be
The 1970 Topps baseball issue sits at a comfortable midpoint in the modern collecting era. It followed the bold 1969 design and preceded the clean black-bordered 1971 set, giving it a transitional look that many hobbyists consider underappreciated. The flagship release covered 720 cards split into three distinct production waves, and the way those waves reached hobby shops across the United States varied dramatically.
Cards numbered 1 through 132 made up the first series, and they hit shelves in decent supply during the early months of 1970. Topps followed up with series two, covering cards 133 through 528, which rolled out through the spring and summer. Series three, the so-called high numbers running from 529 through 720, came last and was distributed in smaller batches through vending boxes rather than loose wax packs. That distribution choice shaped the way survivors were treated by kids and shopkeepers, and it shaped the modern market in turn.
For collectors working in Australia, the practical effect is that high-number cards rarely show up in mixed estate lots from local sellers. Most surviving inventory is held by US-based dealers, with only a thin slice reaching hobby shops in Brisbane, Perth or Hobart through private trades and specialty auctions.
| Series | Card Range | Distribution | Typical Print Run | Common Condition Concerns |
|---|---|---|---|---|
| Series 1 | 1–132 | Wax packs, rack packs | Higher | Centering, wax staining |
| Series 2 | 133–528 | Wax packs, rack packs, cello | Highest | Soft corners, print defects |
| Series 3 (high numbers) | 529–720 | Vending boxes only | Lowest | Off-register printing, edge wear, gum residue |
Breaking down the high number series
The high number series refers specifically to cards numbered 634 through 720, although collectors often use the term loosely to describe all cards released in series three. Topps broke that final wave into multiple printings, and surviving documentation suggests that the lowest print totals sat within the 700-720 range. Card number 700, a Frank Robinson portrait, ended the set on a high note artistically, even if copies in solid shape remain scarce.
What makes the high numbers genuinely hard is not just rarity but also the way vending boxes were merchandised. Each box typically contained 500 cards in stacks of 24, and any short print from those stacks could create gaps that took decades to fill. Children who pulled cards from vending machines in 1970 often stuffed their prizes in pockets, on dashboards, or in bicycle spokes, accelerating wear before the cards ever reached a binder.
Australian collectors chasing the high numbers often rely on local eBay sellers or weekend card shows in Sydney to fill gaps, but the deeper holes almost always require patience and an offshore order.
Production quirks and condition challenges
Anyone who has sorted through a stack of 1970 high numbers notices the design troubles almost immediately. Centering is the most visible issue, with the typical copy running noticeably off to one side. Print registration wandered as the press ran long shifts, leaving ghosting along the borders of cards such as number 655 Boog Powell and number 684 Carl Yastrzemski. Corners on cards from vending boxes tend to be soft and fuzzy rather than crisp, partly because of how the cards were stacked and dispensed.
Backs of the cards often show wax or gum staining that never fully cleaned up, even with professional restoration. Some collectors have noticed faint vertical streaks on the reverse of cards pulled from later printings, suggesting that ink coverage became inconsistent as the run progressed. None of these issues are unique to Topps, but they cluster heavily in the high number wave.
In Melbourne and Adelaide, the small handful of dealers who handle vintage material will usually grade condition more conservatively than US counterparts, simply because replacement copies are so hard to source locally. A card graded PSA 5 might be sold off the shelf at a price an American buyer would expect for a PSA 7.
Star cards and key rookies worth chasing
The high number series carries several cards that any serious vintage collector wants on their want list. The most quoted are the rookie cards, including the John Hiller Rookie Stars card at number 701 and the Bob Boone Rookie Stars card at number 675, both of which routinely appear in auction headlines. Other chase cards include the manager cards at the end of the set, the Roberto Clemente at number 620 which sits just below the high number cut, and the Willie McCovey number 600 milestone card.
Boog Powell, Frank Howard, Willie Stargell, and Pete Rose all appear in the high number run, giving set builders plenty of Hall of Fame talent to chase. Of these, Powell and Stargell tend to be the toughest in high-grade condition because of their wide backgrounds, which expose every printing imperfection.
Australian collectors targeting the Bob Boone Rookie Stars card, for example, will find local market listings hovering around AUD 180-250 in lower grades, while PSA 8 examples usually come from US auction houses at well above AUD 600 once shipping, GST and currency conversion are factored in.
Pursuing the set from an Australian base
Completing a 1970 Topps run from Australia demands a slightly different approach than filling the set from inside the United States. Local hobby shops in Sydney's CBD and Melbourne's inner suburbs tend to carry modern Topps flagships, with Heritage products sometimes stocked through importers who buy direct from US distributors. Vintage singles usually arrive as consignment pieces from estates, and a freshly listed 1970 high number tends to disappear within hours of being posted.
eBay Australia, Facebook collector groups, and the twice-yearly card shows hosted in Brisbane and Perth are the most reliable local channels. For the tougher cards, most Australian collectors end up ordering from overseas sellers, paying close attention to shipping insurance, declared values, and Australia Post tracking. The calendar matters too: ordering during the southern hemisphere winter tends to mean faster clearance through customs, while peak December shipping often adds two to three weeks of buffer time.
Patience tends to win out. Filling the high number series is rarely a sprint, and Australian set builders often spend two to three years hunting down the final cards.
Grading, preservation and long-term value
For collectors who intend to hold the 1970 Topps high numbers long-term, grading is almost always worth considering. The set's notorious centering issues mean that raw cards frequently come back from PSA or SGC with lower numerical grades than expected. A card that looks clean in hand might earn a 5 or 6, while a visibly soft-cornered copy could land a 3.
Storage conditions matter even more in Australia because of the climate. Coastal humidity in Sydney and Brisbane can accelerate paper oxidation, and collectors in those regions often invest in silica gel packets and dehumidified display cabinets. Inland collectors in Adelaide or Canberra generally enjoy drier air, which is gentler on vintage cardboard over decades.
Long-term, the high number series has held its value better than most vintage commons from the era. Even low-grade copies have climbed steadily as supply dwindles, and high-grade rookies continue to outpace the broader vintage market.

If you are working through the 1970 Topps high number series, start by mapping out what you already own and what remains on the want list. Most Australian collectors find that connecting with a few trusted US dealers on a regular basis, combined with monitoring local Australian listings, keeps the project moving forward. The set is famously unforgiving, but it is also one of the most rewarding vintage Topps builds a serious collector can attempt. Browse the Topps Heritage coverage on Baseball Card Blogs to see how Topps has continued to revisit its classic designs in the decades since, and use that perspective to inform how you pursue the originals.
