1. 1914 Babe Ruth Rookie Card

Estimated Value: $200,000+

It should be no surprise that The Sultan of Swat claims the top spot. Before becoming a Yankee legend, Babe Ruth began his career with the Red Sox. The 1914 Babe Ruth rookie card features him in a Boston uniform as a rookie pitcher. Only 12-15 copies are believed to exist.

This card was printed by the Baltimore News newspaper. It pictures Babe winding up, ready to unleash his blazing fastball. The stats on back show his pitching numbers from 1914-1915.

Ruth was mainly a pitcher his first few seasons, before being converted to a slugging outfielder. This rare card captures the earliest days of the Great Bambino's illustrious career.

2. 1975 Fred Lynn Rookie Card

Estimated Value: $15,000 - $30,000

Fred Lynn took MLB by storm in 1975, capturing Rookie of the Year and MVP honors. His 1975 Topps rookie card is the premier card from that year's set. It pictures a young Lynn taking a cut at the plate.

Only a handful of graded GEM-MT 10 examples are known to exist. High-grade copies sell for north of $15,000. Even low-grade copies fetch $3,000+.

Lynn sparked those great 1970s Red Sox teams with fellow star Jim Rice. He smashed 100 homers and batted over .300 in his first five seasons. This rookie card of the AL MVP is a must-have for Sox fans.

3. 1949 Ted Williams

Estimated Value: $10,000 - $15,000

"The Kid" aka "The Splendid Splinter" is arguably the greatest player in Boston history. Williams played his entire 19-year career with the Red Sox. The left-handed slugger was the last player to bat over .400 for a season.

His 1949 Bowman card pictures Williams completing his sweet lefty swing. A .330 career hitter, he belted 521 homers and twice captured the AL Triple Crown. This post-war card of the Red Sox legend can sell for $10,000 or more in top grade.

Few baseball cards capture the combination of scarcity, eye appeal, and legendary subject better than this Ted Williams classic. It's a must own for any serious Boston fan.

4. 1966 Carl Yastrzemski rookie card

Estimated Value: $8,000 - $12,000

His 1966 Topps rookie card pictures him swinging the bat at Fenway Park. High-grade copies can sell for $8,000+. Even low-grade copies are worth $1,000+.

Yastrzemski spent his entire 23-year career with Boston, amassing 3,419 hits and 452 home runs. He was elected to the Baseball Hall of Fame in 1989. This iconic card remains sought after by collectors over 50 years later.

5. 1948 Johnny Pesky rookie card

Estimated Value: $5,000 - $8,000

A member of the Red Sox Hall of Fame, Johnny Pesky was a fan favorite over his 61-year career with the franchise. His 1948 Bowman rookie card pictures him laying down a bunt, showcasing his contact hitting ability.

Pesky hit .307 over 10 seasons as a player. But he's best remembered as a coach and manager for the Sox. He'd later have the right field foul pole named "Pesky's Pole" after him.
