5 Costly Mistakes People Make When Selling Sports Cards Online (And How to Avoid Them)
Selling sports cards online should be simple—but if you want real results, there are a few things you need to get right.
At The Heritage Hockey Vault, we help collectors and families across Canada turn their hockey cards into fair market value without the hassle. We’ve seen firsthand how the right approach can lead to great returns—and how common mistakes can leave money on the table.
Whether you're managing an inherited collection or clearing out your extras, here are 5 common mistakes to avoid when selling sports cards online:
🔎 1. Low-Quality Photos and Weak Descriptions
The Mistake: Blurry photos. Bad lighting. No details. Buyers scroll right past when listings look unprofessional or unclear.
Our Tip: Take sharp photos of the front and back in natural lighting. Use a clean background. Mention any flaws or highlights in your description—like corners, edges, centering, or surface scratches. Honesty builds trust, and trust builds sales.
💸 2. Overpricing Cards Based on Emotion (or Wishful Thinking)
The Mistake: Pricing cards way too high just because someone else listed theirs for a big number.
Our Tip: Focus on what similar cards actually sold for, not what someone hoped to get. Check recent sales on eBay or trusted marketplaces. Be realistic—overpriced cards just sit unsold, and buyers move on.
⏳ 3. Holding Cards Too Long Waiting for the "Perfect" Time
The Mistake: Waiting for your card to hit a mythical peak that may never come. You end up missing the ideal time to sell.
Our Tip: If a player is hot now, don’t wait. Strike while demand is high. Card values often drop fast after a playoff run, milestone, or brief media buzz.
🔥 4. Getting Caught in the Hype (Instead of Using Logic)
The Mistake: Letting social media hype or YouTube speculation drive your selling decisions.
Our Tip: Focus on a player’s track record, potential longevity, and rarity of the card. If your gut says the hype feels shaky—trust your instincts. Always back decisions with data.
🚫 5. Grading Low-End or Junk Wax Cards
The Mistake: Spending $15–30 to grade a common card from the ‘80s or ‘90s with little to no resale value.
Our Tip: Most mass-produced cards from that era—even in great shape—won’t bring back more than the grading fee. Save grading for rare rookies, vintage stars, or cards that will genuinely benefit from authentication.
