Old Baseball Cards on Twitter: Here are Ten Vintage Accounts to Follow

With a collection of this magnitude, other Hall of Fame rookies, stars, and set completions from the era could also be in the mix, making every box a potential treasure chest. Here’s a step-by-step guide of what I’d personally do in a situation such as this:


Step 1: Set Up a Strategy

With one million cards, diving in without a plan can lead to chaos. Instead, break the task into manageable steps:

• Create a Workspace: Find a space to sort and organize—whether it’s a garage, basement, or dedicated room. Make sure it’s clean and free of humidity to protect the cards.

• Gather Supplies: You’ll need boxes, dividers, penny sleeves, and top loaders to organize and protect valuable cards. A magnifying glass and reference guide or app for card identification will also come in handy.


Step 2: Start Sorting

The best way to approach a collection this size is by sorting in layers:

• Era: Start by dividing the cards into decades (1970s, 1980s, etc.).

• Sets or Players: Group cards by year, set, or notable players. This will help identify valuable pieces and complete sets.

• Condition: Look for cards in excellent condition, as this significantly impacts their value.


Step 3: Research Values

Once the sorting is underway, research key cards using tools like PSA’s population report, eBay’s sold listings, or price guides such as Card Ladder or Beckett. Keep an eye out for high-value rookies and stars, especially cards in excellent condition.


Step 4: Decide What to Keep or Sell

After identifying the most valuable pieces, decide on your priorities:

Keep: Hold onto sentimental favorites or cards with high potential for appreciation.

Sell: Consider selling duplicates or less-desirable cards through platforms like eBay, COMC, or local card shops. Grouping cards into lots by player or team can appeal to targeted buyers.


Step 5: Enjoy the Journey

Sorting through such a vast collection can be overwhelming, but it’s also an incredible opportunity to rediscover history and uncover hidden treasures. Take it one box at a time, and enjoy the process of connecting with the hobby.

The Hobby Impact

This million-card purchase reflects the resurgence of enthusiasm in the card-collecting community. High-profile acquisitions like this inspire others to explore their collections, dig into vintage sets, and perhaps even take on ambitious projects. With patience, research, and organization, this collector has the potential to turn their overwhelming haul into an enviable collection or a profitable venture.

So, where would you begin if this collection landed in your lap? Whatever the strategy, one thing is certain: the adventure of discovery is priceless!
