Straight answers to the questions every collector and investor asks. No fluff, no gatekeeping — just what you need to know.
Is sports card investing actually profitable?
It can be — but it depends on strategy, timing, and discipline. Like any market, card prices go up and down. The collectors who consistently profit tend to buy based on data (real sold comps, not listing prices), sell into hype spikes, and avoid chasing trends after they've already peaked. The Wax Street exists to give you that data edge. We track real eBay sold prices daily so you can make decisions based on what cards actually sell for, not what someone hopes to get.
How do I know when to sell a card?
The best time to sell is usually when demand spikes — after a breakout game, a trade to a contender, or award season buzz. These spikes are temporary. At The Wax Street, we flag "Sell Into the Spike" opportunities daily: cards that have surged in price and are likely near their short-term peak. If a card has doubled in a week on hype alone, that's usually a better time to sell than to hold and hope.
What's the difference between raw and graded cards?
A raw card is ungraded — straight from the pack or a private sale, with no professional assessment of condition. A graded card has been submitted to a grading company (PSA, BGS, SGC) who assigns a condition score (1-10). Graded cards, especially PSA 10s, typically command significant premiums because the grade is verified and the card is sealed in a protective case. For investing, graded cards are generally easier to buy and sell with confidence because the condition is standardized.
How does The Wax Street track prices?
We scrape actual eBay sold and completed listings every single day. Not listing prices (what people hope to get), not algorithmic estimates — real transactions between real buyers and sellers. We track 300+ sold listings per day across 10+ players, then analyze price trends, volume changes, and market signals. This data powers our daily newsletter, top movers feed, and buy/sell recommendations.
What sports and players do you cover?
We currently cover NFL (our primary focus), MLB, and NBA. We track a curated watchlist of players — established veterans, breakout candidates, and rookies. Our coverage is expanding, and we prioritize players where there's real market activity and card movement. You can see every player we track on our Players page.
What does PSA 10 mean and why does it matter?
PSA 10 is the highest grade assigned by Professional Sports Authenticator, the most widely recognized card grading service. It means the card is in "Gem Mint" condition — perfect centering, sharp corners, clean edges, and no surface flaws. PSA 10s are the gold standard for sports card investing because they're the most liquid (easiest to buy and sell) and typically hold or increase in value better than lower grades. A PSA 10 can be worth 2-10x more than the same card in PSA 9.
How much money do I need to start investing in sports cards?
You can start with as little as $10-20. Not every card needs to be a high-end rookie auto. Some of the best flips come from $5-30 cards that spike after a big game or breakout performance. The key is buying smart — using real sold data to find undervalued cards, not overpaying based on hype. Our free newsletter highlights opportunities at every price point.
What's the difference between a rookie card and other cards?
A rookie card (RC) is a player's first officially licensed trading card, typically released during their first professional season. Rookie cards are the cornerstone of sports card investing because they carry the most long-term upside. As a player's career develops, their rookie cards tend to be the ones that appreciate the most. Not all rookie cards are equal though — parallels, autos, and numbered versions carry premiums over base rookies.
Should I buy cards before or after a big game?
It depends on your strategy. Buying before a big game is higher risk but higher reward — if the player has a breakout performance, the card can spike immediately. Buying after a big game means you're paying the post-hype premium. At The Wax Street, our "Buy It Before the Box Score" section highlights cards to grab before game performance drives prices up, and our Game Day Impact feed shows exactly how stat lines moved the market after the fact.

Where should I buy and sell sports cards?
eBay is the largest and most liquid marketplace for sports cards — it's where most price data comes from and where you'll find the best selection. Other options include COMC (Check Out My Cards) for consignment, MySlabs for graded cards, and local card shows for in-person deals. For selling, eBay auction format often gets you the best price on hot cards, while Buy It Now works well for established comps. All of The Wax Street's price data comes from eBay sold listings because it's the most reliable measure of true market value.
