The 1902 edition of the American Card Catalog baseball card price guide was truly a groundbreaking publication that helped establish the early market for vintage baseball cards and provided collectors with valuable information on estimated values during the early collecting boom of the late 19th/early 20th century. Published annually between 1899-1903, the ACC guides were some of the earliest extensive price lists and set guides for baseball cards produced during the tobacco era from 1868-1918.

While today we take for granted the abundance of online price guides, databases, auction records, and forums that provide a wealth of information for collectors, collectors in 1902 had very limited resources when it came to understanding the relative scarcity and value of different baseball cards from the early tobacco issues. The ACC guides helped address this need by providing collectors with detailed set listings that assigned estimated price ranges to cards from various tobacco brands like Old Judge, Goodwin Champions, Sweet Caporal, etc.

The 1902 edition covered cards printed between 1880-1901 and provided pricing information for an estimated 15,000 individual tobacco era cards. Some of the key highlights and aspects of the 1902 ACC baseball card price guide include:

It was the first guide to provide pricing data on the newly released 1901 issue cards, including stars like Nap Lajoie, Cy Young, and Honus Wagner. Estimated prices ranged from 50 cents to $1.25 depending on the player.

Detailed listings and pricing for the inaugural T206 White Border set from 1909, even though the cards would not be released for another 7 years. This helped build early collector interest and demand for what would become one of the most iconic sets ever made.

Recognition that older tobacco issues from the 1880s and early 1890s had become very scarce and difficult to acquire. Cards like the 1883 Old Judge Billy Sunday were priced at an eye-popping $5, one of the highest individual card prices listed.

Assigning the first documented price range estimates for complete tobacco sets, with prices ranging from $15-$50 depending on condition, brand, and year. This helped establish the concept of set building and completion as a collecting goal.

Notation that star player cards tended to trade hands for higher prices than lesser known players. Stars of the day like Cy Young and Nap Lajoie routinely fetched double or triple the estimated value of a typical common player card.

Detailed condition guidelines that described the differences between graded states like Mint, Fine, Good, Poor. This was one of the earliest attempts to standardize condition terms for collectors.

A section dedicated to the newly emerging field of cabinet cards – larger format photos of ballplayers produced as collector cards in the 1890s. Early star cabinet cards earned estimated values up to $3 each.

Notation that while supply was dwindling, new discoveries of older stock could still be found in tobacco shops, drugstores and general stores across the country. This encouraged continued searching and helped fuel the growing collector marketplace.

In addition to providing the earliest known pricing data, the 1902 ACC guide helped shape the collecting field by establishing some foundational concepts that are still used today – standardized condition scales, set and player collecting, recognition of stars vs commons, and the growing scarcity and value of early tobacco issues. For collectors of the time, it would have been an invaluable resource to understand relative values, track market trends, and make informed purchases as the collecting boom took hold. While raw prices have increased many times over, the 1902 ACC baseball card price guide was truly the pioneering work that helped launch the hobby into the collecting phenomenon it remains over a century later.
