We talk a lot here at The TCG Times about what works. The blue chips, the safe holds, the patterns that repeat in our favour. But there is just as much to learn from the other side the “dark side” if you will. So let us take a walk through five years of genuinely bad TCG investments, not bad luck, not unforeseeable market shifts, but decisions that, with a bit of hindsight, were completely avoidable from the start. We have grouped these into the recurring categories of mistakes we see over and over… and over again, with a specific case study attached to each one, because the pattern matters more than the individual cards.
Mistake #1: Buying the Hype Peak, Not the Card
Yeah, it’s a basic one, but let us get it out the way, you might even learn something new. This is the single most common way money gets lost in this hobby, and it happens in a super predictable, repeatable way every single time a card goes viral. A creator, a tournament result, or a celebrity moment triggers a buying frenzy (good if you have the card). The price goes vertical. Buyers who were not paying attention before suddenly are, and they buy in at the absolute top because the excitement is at its loudest exactly when the price is at its highest.
Case study: Early 2021 Charizard mania purchases. During the height of the pandemic driven boom, raw and lightly graded Base Set Charizards were changing hands at prices that, in hindsight, represented a genuine market top for that specific window. Collectors who bought during the peak weeks of that frenzy, rather than the steady, longer-term climb the card has shown since were often sitting on paper losses for a year or more before the broader market caught back up to those levels. The card itself was never the problem. The timing was everything. Sellers made a lot of money; buyers are still sitting waiting for the long game to kick in, and possibly won’t be for a few years, depending on what they bought and at what price..
Mistake #2: Chasing Modern Sealed Product During Its Hype Window
We covered this dynamic directly in our piece on the $2 pack problem, the moment a set is hardest to find and most aggressively scalped is precisely the moment publishers are most likely to be pumping up production to meet that demand. Buying sealed products at the absolute peak of a hype cycle, before the print run catches up, has burned a significant number of collectors over the past five years.
Case study: Several 2021-2022 mainline Sword & Shield era boxes. Several boxes purchased well above MSRP during their peak scarcity window saw very notable corrections once supply caught up with demand through 2022, leaving buyers who paid the scalper premium underwater for an extended period, even as the broader hobby eventually recovered.
Mistake #3: Ignoring Reprint Risk on Competitively Relevant Cards
This is more of a Yu-Gi-Oh-specific trap that we have flagged repeatedly, including in our deep dive on the reprints trap. A card being powerful and in demand does not make it a good investment if the publisher’s standing policy is to keep reprinting it to serve the competitive playerbase. Konami and reprints go hand in hand. And it can be seen as a good or bad thing depending on your own personal situation.
Case study: Mid-rarity format staples bought at first-print prices. Investors who picked up commonly played staple cards at their initial, pre-reprint secondary market price, betting on continued competitive relevance driving the price hike have repeatedly watched those same cards get reprinted (it’s a rough one if you have been in this position) in a structure deck or tin within a year or two, completely ripping the price back toward bulk standards. The card stayed exactly as good competitively. The investment thesis collapsed anyway, because rarity, not playability, was always the real driver of price.
Mistake #4: Holding Past the Obvious Exit Point (The Sunk Cost Trap)
We wrote an entire piece on the psychology behind this one, the sunk cost trap, but it deserves a place here too because it has quietly destroyed more portfolios over the past five years (a portion of our own have fallen victim) than almost any single bad purchase decision. It is not the buying that hurts most collectors. It’s the refusal to sell once the original thesis has clearly broken down, purely because admitting the loss feels worse than continuing to hold. Kind of like being stuck in limbo, not a great feeling.
Case study: Pandemic-era speculative grading submissions. A wave of collectors submitted bulk and mid-value cards for grading during the 2020-2021 boom, expecting the elevated market to absorb the submission costs comfortably. When the broader correction hit in 2022, a significant number of those graded cards were worth less than the combined cost of the card and the grading fee, yet many holders kept them rather than realising the loss, waiting for a recovery to a price point that, for many of these cards, never fully returned. Imagine holding 100s of slabs of graded bulk…
Mistake #5: Trusting Influencer Conviction Over Independent Research
We covered the mechanics of this directly in our piece on TCG content creators, but it is worth restating plainly here, following a creator’s “it’s time to buy” call without independently verifying the fundamentals has been one of the most consistent value-destroyers of the past five years, particularly because a meaningful number of those calls came from people who already held the position they were promoting. To break it down, they are pumping the value of their own cards, then selling them. The prices usually drop back to their original price a day or a week later.
Case study: Multiple “next big thing” set predictions. Several modern sets were heavily promoted by prominent creators as the “next Evolving Skies” or “next breakout chase set” in the months following their release, driving short-term buying pressure on the back of that framing. (note not all creators are like this, but some obvious ones come to mind…)The overwhelming majority of these predictions did not play out, most modern sets do not become generational holds, by simple statistical reality, especially with so many sets being released each year, they all can’t be winners. And buyers who entered based on creator enthusiasm rather than the underlying fundamentals were often left holding cards well above their settled long-term market price. Most of these people are just looking to make a quick and easy buck. It doesn’t work like that.
The Common Thread
Look back across all five of these categories, and the same root cause keeps appearing in different ways, emotional decision-making overriding fundamentals. Buying because everyone else is buying. Holding because selling feels like losing. Trusting a confident (loud) voice over your own research. None of these mistakes required bad luck. Every single one of them was avoidable with a bit of distance from the moment and a clearer set of questions asked before the purchase, not after.
The TCG Times’ Verdict: Study the Losses as Closely as the Wins
We spend a lot of time on this site celebrating the cards and strategies that have worked. This list exists because the losses teach faster and stick harder (like thousands of $ harder). If you recognise your own past decisions in any of the five categories above, that is not a reason to feel discouraged. We have made all of these mistakes at some point, it happens, that’s why we are confident to talk about it, so you don’t make the same mistakes we did. Every serious investor in this hobby has a version of this list somewhere in their own history. The goal is simply to make sure your next five years of decisions are informed by this one, rather than repeating it.
