The values of 1979 baseball cards can vary widely depending on the player, the condition and grade of the specific card, and other factors. The 1979 set is not one of the most valuable sets from the 1970s but it does contain some very valuable rookie and star player cards.

One of the most valuable cards from the 1979 set is the Wayne Garland rookie card. Garland was an All-Star pitcher who had a lot of potential early in his career before injuries derailed him. His rookie card in near mint condition could be worth $1000-1500. Another high value rookie is Donruss #526 Robin Yount who had a Hall of Fame career. Mint condition examples of his rookie fetch $800-1000.

Star players from the era like Reggie Jackson, Mike Schmidt, and Nolan Ryan have cards in the $50-150 range depending on condition. High grade examples of their main centered cards could reach $200-300. Rookies of pitchers Bob Welch and Dave Righetti have values of $30-80 and $50-150 respectively based on grade.

Two of the most visually striking cards are the Kenny Mayne and Bobby Bonilla O-Pee-Chee rookie variations, which picture the players in action and have pink or blue borders instead of the typical red. High quality versions of these scarce variations can sell for $200-500. More common stars in the set include George Brett, Steve Garvey, Joe Morgan, and Dave Parker who have cards valued between $10-40 usually.

While the set overall isn’t overly expensive, it does contain the rookie cards of Hall of Famers like Don Mattingly, Rickey Henderson, and Ozzie Smith. Mint Donruss #1 Don Mattingly rookies sell in the $150-250 range now depending on centering and corners. Near perfect PSA 10 graded examples can reach $500-1000. Rickey Henderson’s rookie card values are similar at $150-250 for a high quality example.

Ozzie Smith’s 1978 rookie from Donruss is also quite desirable in the hobby. PSA 9 versions are $150-200 while a PSA 10 graded Ozzie Smith rookie could command $300-500. Another key factor that influences 1979 card values are whether the card is from Topps, Donruss, or one of the Canadian or Japanese variations that were produced that year.

Condition is obviously very important too. Even star player or rookie cards in poor condition may only be worth $5-10, while pristine near mint to mint versions fetch the higher prices outlined above. The inclusion of playoff or World Series statistics on the back can also add value. Factors like centering, corners, edges and surface also impact grades from services like PSA and SGC. Cards receiving high numerical grades universally sell for higher amounts.

While the 1979 set as a whole may not have quite the cachet of earlier ’70s years like 1975, it still contains some very affordable star and future Hall of Famer rookie options. With prudent shopping and patience, a collector can build an intriguing collection from this year for a reasonable budget. Top tier gems like a PSA 10 Wayne Garland or perfect Don Mattingly rookie could provide thrills too. Values may trend upwards a bit long term as more collectors gain nostalgia for their childhood collecting era of the late 1970s.
