Ever walked into a store, saw a shelf full of generic white t-shirts, and thought, "These are a dime a dozen"? You aren't alone. We say it all the time. It’s one of those phrases that just rolls off the tongue when we want to describe something that isn’t exactly a "limited edition" find. Basically, it means something is so common that it has almost no individual value. It’s abundant. It's cheap. It's everywhere you look.
But have you ever actually stopped to think about the literal math there? A dime. For twelve. That is less than a penny per item. In the 1800s, that was actually a thing. You could walk up to a produce stand and walk away with a massive haul of peaches or eggs for a thin silver coin. Today? Good luck getting a single organic apple for less than two bucks.
Where the Heck Did "A Dime a Dozen" Actually Come From?
Language is a weird, living creature. The a dime a dozen meaning we use today evolved from a literal price point into a metaphorical insult. Back in the early 19th century—specifically around the 1860s in the United States—it wasn't an idiom. It was just an advertisement.
According to the Oxford English Dictionary and various historical price indexes from the mid-Victorian era, goods like oranges, eggs, and even certain types of hardware were frequently sold at this rate. Imagine being able to feed a whole family breakfast for ten cents. It sounds like a dream now, but back then, it meant the supply was overflowing. If a farmer had too many eggs and not enough buyers, the price plummeted.
By the turn of the 20th century, the phrase started to shift. People began using it to describe things that weren't for sale. If you called a type of person or a specific idea "a dime a dozen," you were essentially saying they weren't special. You were saying they were replaceable.
The Economics of Commonality
Supply and demand. That’s the heart of it. When something is rare, we crave it. When it’s everywhere, we ignore it.
Think about "influencers" on social media. In 2010, being a travel blogger was unique. It was rare. Now? Travel vloggers are a dime a dozen. You can't throw a rock in Bali without hitting someone holding a gimbal and talking to a front-facing camera. Because the market is saturated, the perceived value of any individual vlogger has dropped significantly, unless they have a truly unique hook.
Why We Use the Phrase Even When Prices Change
Inflation is real, but idioms are stubborn. We don't say "a twenty-dollar bill a dozen," even though that might be more accurate for the price of eggs in a modern grocery store during a supply chain crisis. We stick to the dime.

Why? Because "dime" has a phonetic punch. It’s snappy. It carries the weight of being the smallest "significant" coin. A penny is almost worthless on its own, but a dime feels like the start of real money—or at least it did in 1920. Using this specific phrase allows us to dismiss something with a bit of a sting.
It’s often used in a derogatory way.
- "Guys like him are a dime a dozen in this town."
- "App ideas are a dime a dozen; execution is what matters."
In that second example, which is a favorite in the tech world (shout out to the ghost of Steve Jobs and various Y Combinator mentors), the idiom serves a specific purpose. It’s a reality check. It reminds us that having an idea isn't the hard part. Millions of people have ideas. The "commonness" of the idea makes it worthless without the rare "effort" of building it.
Common Misconceptions About the Phrase
People often get the origin mixed up with the "Baker's Dozen." Let’s clear that up right now. A Baker’s Dozen is thirteen. That comes from old English laws (the Assize of Bread and Ale) where bakers gave an extra loaf to avoid being whipped for accidentally short-changing customers.
"A dime a dozen" has nothing to do with being generous or giving extra. It’s strictly about things being so plentiful they are cheap.
Another weird one? People sometimes think it’s a British phrase. It’s not. The dime is a uniquely American (and Canadian) coin. The British equivalent would be something like "ten a penny," which carries the exact same weight. If you're in London and you say "a dime a dozen," people will know what you mean because of Hollywood, but they’ll also know you’re an American.
The Psychological Toll of Being "Dime a Dozen"
There is a dark side to this. In the modern job market, many workers feel like they are a dime a dozen.

Automation and global outsourcing have made it so that many skill sets—even ones that used to be considered "high level"—are now viewed as commodities. If you’re a basic data entry clerk or a junior graphic designer using templates, you might feel the weight of this idiom. It’s a scary feeling. It’s the feeling of being "fungible."
Economics professor Tyler Cowen discusses this concept in his book Average is Over. He argues that as we move further into a tech-driven economy, the "middle" gets hollowed out. You’re either rare and valuable, or you’re part of the crowd that’s a dime a dozen.
Spotting the Pattern in Pop Culture
If you look at movie tropes, you'll see this phrase used as a classic "villain vs. hero" dialogue line.
"Heroes like you are a dime a dozen, kid."
The villain says this to demoralize the protagonist. They want the hero to feel small. They want them to feel like their sacrifice doesn't matter because there will just be another one along in five minutes.
But here is the irony. In the world of cinema, the villains who say that are actually the ones who are a dime a dozen. We’ve seen that archetype a million times. The "tough guy who thinks everyone is replaceable" is one of the most common cliches in writing. Honestly, it’s a bit of a meta-joke.
How to Stop Being "A Dime a Dozen"
If you feel like your business, your brand, or your skills fall into this category, you have to pivot. You have to find the "purple cow," as Seth Godin would put it.

- Hyper-Specialization. Don't just be a "writer." Be a "technical writer for subsea fiber optic cable companies." There are only about five people who can do that. You are no longer a dime a dozen. You are one in a million.
- The Human Element. In the age of AI, "content" is a dime a dozen. I could generate ten thousand words of fluff in three seconds. But authentic, lived experience? That’s rare. People want to hear from humans who have actually bled, sweated, and laughed.
- Price Positioning. Sometimes, being a dime a dozen is a choice. If you compete on price, you are choosing to be a commodity. If you raise your prices and back it up with insane quality, you move out of that category.
Real-World Examples of Commodity vs. Rare
Look at the diamond industry. Diamonds are actually fairly common in the Earth's crust. For a long time, they were headed toward being "a dime a dozen" (relatively speaking).
Then De Beers stepped in. They controlled the supply. They created the "A Diamond is Forever" campaign. They manufactured scarcity. They took something that was becoming common and made it feel rare. It was a marketing masterstroke that changed the a dime a dozen meaning for an entire gemstone.
On the flip side, look at digital photos. In the 90s, taking a photo was an event. You had 24 frames on a roll of film. You paid to develop them. Each photo was precious. Now? Photos are a dime a dozen. We have 40,000 images in our iCloud storage that we never look at. Because they are so common, the value of a single snapshot has plummeted.
Actionable Takeaways for Your Life
Understanding the a dime a dozen meaning isn't just a vocabulary lesson. It's a lens through which to view your value in the world.
- Audit your output. If you are producing work that anyone else could do with an hour of training, you are in the "dime a dozen" zone. Move toward "high-barrier-to-entry" tasks.
- Listen for the phrase. When someone says it, they are signaling what they value. If a client says, "Graphic designers are a dime a dozen," they are telling you they don't value design. Don't try to convince them; find a client who knows that good design is rare.
- Embrace the common when it’s useful. Not everything needs to be rare. Sometimes you just need a dozen eggs. Sometimes you just need a standard screwdriver. There is a time and place for the abundant.
In the end, the phrase is a reminder that value is subjective and often tied to how hard something is to replace. If you want to be worth more than a fraction of a cent, you have to find a way to be the thing that can’t be found on every street corner.
Take a look at your current project or career path. Ask yourself: "If I disappeared tomorrow, could my boss or my customers find twelve more of me by lunchtime?" If the answer is yes, it is time to differentiate. Start by identifying one specific skill you have that others find difficult or annoying to learn. Lean into that. That is how you break out of the "dozen" and become the "one."
The market for "average" is always crowded. The market for "exceptional" is usually pretty empty. Move where the people aren't.
