The 1975 baseball card set is considered one of the most valuable sets from the 1970s due to several high-profile rookie cards that were issued that year. Some of the most valuable and sought after 1975 baseball cards that can be quite valuable depending on the grade and condition of the card include:

George Brett rookie card – Brett had a Hall of Fame career with the Kansas City Royals and is considered one of the best third basemen ever. His rookie card is among the most valuable from the 1970s. In Near Mint-Mint (NM-MT) condition, it can fetch upwards of $1,500. In gem mint condition grades, the Brett rookie has sold for over $6,000.

Dave Parker rookie card – Parker was a power-hitting corner outfielder who won two batting titles in the 1970s. He had a long, productive career. Like Brett’s, his rookie is one of the most iconic from the decade. In top condition, it can sell for over $1,000 but more typically in the $300-500 range.

Randy Jones rookie card – Jones won the Cy Young Award in 1976 with a 22-14 record. Not a huge star otherwise but his rookie is still regarded as one of the scarcer cards from 1975. Expect to pay $500-750 for a high-grade copy.

Don Money rookie card – Money was a slick-fielding second baseman for Milwaukee and had some good years at the plate. His rookie paper card attracts collectors since it features a fun action pose. Near-mint copies can sell for $250-400.

Ken Brett rookie card – The younger brother of George Brett, Ken had some solid seasons with the White Sox and A’s during his career. His rookie is also seen as desirable, fetching $200-300 in top condition.

Robin Yount rookie card – Yount went on to a Hall of Fame career primarily with the Brewers and his rookie is exceedingly sparse in top-graded form. Even poorly graded copies sell for $100-plus due to the star power of Yount’s career.

Paul Molitor rookie card – Molitor put together a remarkable 21-year career that saw him collect over 3,000 hits. His rookie is tough to find pristine and is valuable, with high-quality copies valued at $300-500.

Kirk Gibson rookie card – Gibson made his name with the Tigers initially but would have his best seasons with the Dodgers later, whiffing a game-winning home run in the 1988 World Series. Top-quality 1975 rookie cards sell for $200-350.

Those are some of the headliners from 1975 but there are other valuable rookie cards as well, such as Chili Davis, Gary Carter, Joe Charboneau, Goose Gossage and Garry Maddox, among others. Beyond the rookies, stars featured on popularly traded 1975 cards that can have value based on condition include Johnny Bench, Pete Rose, Steve Garvey, Carlton Fisk and Reggie Jackson.

Notably, the 1975 set has two separate issues – Topps and the less common OPC (O-Pee-Chee) release distributed in Canada through concessions and vending machines. The OPC cards are scarcer and hold a premium, often doubling typical values when compared to the same player’s Topps card from that year. Unlike many sets of the time, the 1975 Topps featured photo variations, which can spike the value of certain serial numbered or action pose variation cards after accounting for condition and scarcity.

Factors like grade/condition, subsets, autographs or serial numbers all play a role in a card’s value and dollar amounts can vary widely based on those attributes. Generally speaking though, high-quality, well-centered 1975 cards of the aforementioned rookies and stars that grade NM-MT 7 or above can be reasonably expected to fetch hundreds of dollars according to market comparables. Price guides and recently sold eBay listings are good resources for discerning typical prices – but condition and demand will always influence specific values.

The 1975 Topps and OPC baseball card sets remain among the most collectible issues from the 1970s due to career accomplishments of players whose careers had only just begun at that point. Keys like the George Brett, Dave Parker and Robin Yount rookies consistently command four-figure sums when pristine. Other star players or scarce parallels and variations beyond the typical base issue ensure significant values can be realized for condition sensitive versions of many others cards from this alluring vintage release as well.
