Frequently Asked Questions
Where is the best place to buy sports cards online?▾
It depends on the card value. For cards under $20, eBay or Mercari offer the most selection and competitive pricing. For $20-$200, COMC (Check Out My Cards) lets you inspect high-res scans before buying — eliminating condition surprises. For $200+, eBay with authenticity guarantee or Whatnot live auctions often produce the best deals. Facebook groups offer the lowest fees (0%) but require trusting the seller. Always factor in shipping costs, platform fees, and buyer protection when comparing prices across platforms.
How do I avoid buying fake or counterfeit sports cards?▾
For graded cards (PSA, BGS, CGC, SGC): verify the certification number on the grading company website, check slab weight and font consistency, and look for hologram security features. For raw cards: examine print quality under magnification, check card stock thickness, compare to known authentic examples, and be wary of deals that seem too good to be true. Buy from established sellers with positive feedback history. Vintage cards (pre-1980) require extra scrutiny for trimming, re-coloring, and alterations.
How do I know if I am paying a fair price for a sports card?▾
Check recent sold listings on eBay (not active listings — those are asking prices, not market prices). Filter by "Sold Items" and match the exact card, condition, and grade. Look at the last 5-10 sales to establish a range. For graded cards, PSA's price guide and 130point.com provide historical sales data. A fair price is within 10% of the median recent sold price. Be cautious of cards priced 30%+ below market — they may be counterfeit, damaged, or misrepresented.
Should I buy raw or graded sports cards?▾
Buy graded if you want certainty of condition and authenticity — graded cards have verified grades and tamper-evident slabs. Buy raw if you are comfortable assessing condition yourself and want to save money (raw cards are typically 30-60% cheaper than graded). For cards worth $100+, buying graded (PSA 9 or 10) protects your investment. For cards under $50, buying raw and grading yourself can yield better returns if you can accurately assess condition.
What should I check before buying a card at a card show?▾
Bring a loupe or magnifying glass to inspect centering, corners, edges, and surface. Compare the asking price to recent eBay sold prices on your phone. Check for soft corners, surface scratches, print defects, and off-center borders. For graded cards, verify the cert number on the spot using the grading company app. Negotiate — dealers expect it, especially later in the day or on the last day of a multi-day show. Ask about bulk discounts if buying multiple cards.
