Internet Brain Rot, Part 1: How GEM 10 Hype Is Warping What Your Trading Card Collection Is Really Worth

If you're considering bringing a trading card collection to sale, you've probably watched a video like this: a guy holds up a slab, the thumbnail is dripping with dollar signs, and the pitch is some version of "I found this $2 card at Walmart and it just sold for $500 GRADED." It's the trading card equivalent of a Jim Cramer stock pick: loud, confident, and engineered to trigger action, not understanding. And it's quietly warping how sellers understand what their collection is actually worth before bringing it to market.

This is the first entry in a series about how the internet is breaking people's brains when it comes to understanding the real value of their collectibles. If you're trying to figure out how much your card collection is worth, or you're preparing to sell a trading card collection for the first time, grading hype is one of the biggest traps standing between you and an accurate collection valuation. We're starting here because it's the clearest, most measurable example of the problem: a hype-driven expectation gap that costs sellers real money every time they submit a card without understanding the odds.

Understanding Why Grading Odds Matter Before You Sell Your Collection

The myth is that grading is basically a done deal for getting rich, and that belief shapes how sellers price their cards before they ever bring a collection to market. The math says otherwise. Across the hobby's largest grading population data set, GemRate reported a 34% gem rate (PSA 10) through the first half of 2025 across 5.1 million cards graded, down from a 40% gem rate on 11.4 million cards graded in all of 2024. That sounds almost decent until you realize gem rate is a blended average propped up sky-high by modern, mass-produced Pokemon and TCG product graded in bulk, not by the vintage sports cards and older non-sports cards that make up most collections coming to market for evaluation.

Break it down by era and the picture that matters for collection valuation changes dramatically. Data compiled from GemRate's 2023 grading statistics showed PSA 10 rates by decade of print: roughly 14.1% for 1990s cards, 20.9% for 2000s cards, 50.5% for 2010s cards, and 68.9% for 2020s cards. Flip that around: a card printed in the 1990s has roughly an 86% chance of NOT coming back a 10 — which matters enormously if you're trying to determine what your card collection is worth before deciding whether to grade or sell raw.

Individual card examples make the point even sharper for anyone evaluating a collection for sale. A widely cited breakdown of a 1993 Topps Derek Jeter showed 54,000 cards graded by PSA with only 3,700 coming back a 10 — a 7% gem rate. Another example from the same analysis was even more brutal: a card with 43,000 submissions and only 25 PSA 10s ever awarded, a 0.06% gem rate. That's not "the vast majority of the time you won't get a 10." That's "you are functionally never getting a 10," full stop — and it's exactly the kind of detail a professional appraisal catches before you make a costly grading decision.

The Truth: You Are Not Getting Gem 10 Grades When Selling Your Collection

The takeaway for anyone evaluating a collection to sell: the "you won't get a 10" framing isn't hyperbole for a lot of real, commonly submitted cards. It's closer to literal truth for vintage and mid-tier modern material; exactly the kind of inventory most sellers bring to market when they consign or sell a card collection. Pricing a raw/ungraded card collection according to the Gem 10 column is not only going to skew the value of the collection high, it's going to be off by orders of magnitude, maybe by as much as 10x! It's not a realistic picture of the actual value of the collection.
