Lesson 2: What Gives Money Its Value?
About 30 minutes — Discussion-based lesson
What You Will Learn
By the end of this lesson, you will be able to:
- Explain why a piece of paper can be worth $20
- Distinguish between intrinsic value and assigned value
- Describe what happens when people lose trust in money
- Understand the role of government in backing currency
Why Is a $20 Bill Worth $20?
Pick up a dollar bill and really look at it. It is a small piece of paper with ink on it. The paper itself costs almost nothing to make. So why can you walk into a store and trade it for a sandwich, a book, or a toy?
The answer is trust. Everyone around you — the store owner, the sandwich maker, the bus driver — all agree that this piece of paper is worth something. That shared agreement is what gives money its power.
Discuss Together
If you found a $100 bill on a deserted island with no stores and no other people, would it be worth anything? What would actually be valuable on that island?
Intrinsic Value vs. Assigned Value
There are two ways something can be valuable:
Intrinsic Value: Value that comes from the thing itself. A bottle of clean water has intrinsic value because you can drink it. Food has intrinsic value because it keeps you alive. Gold has some intrinsic value because it is useful in electronics and jewelry.
Assigned Value: Value that people agree to give something. A $20 bill has assigned value — the paper is not useful on its own, but everyone agrees it is worth $20. Trading cards, rare sneakers, and brand-name items also get much of their value from what people agree they are worth.
Intrinsic vs. Assigned Value Examples
| Item | Intrinsic Value | Assigned Value |
|---|---|---|
| Water | High (you need it to survive) | Low (usually cheap) |
| Diamond ring | Low (you cannot eat or drink it) | Very high (people agree it is valuable) |
| $100 bill | Almost none (just paper) | $100 (by agreement) |
| Bread | Medium (nutritious food) | Low (a few dollars) |
Try It: Value Sort
For each item below, decide: does it have mostly intrinsic value, mostly assigned value, or both?
- A glass of clean water in the desert
- A rare baseball card
- A warm winter jacket
- A $50 gift card
- Water in the desert: Very high intrinsic value (survival need)
- Rare baseball card: Almost entirely assigned value (people agree it is worth money because it is rare)
- Winter jacket: High intrinsic value (keeps you warm) plus some assigned value (brand names cost more)
- $50 gift card: Entirely assigned value (just a piece of plastic, but the store agrees it is worth $50)
What Happens When Trust Breaks Down?
If money depends on trust, what happens when people stop trusting it? This has actually happened many times in history. When a government prints too much money, each bill becomes worth less and less. Prices go up, and people need more and more bills to buy the same things.
When Money Loses Value
In some countries, prices have risen so fast that people needed wheelbarrows full of cash to buy basic groceries. This is called hyperinflation, and it happens when trust in a currency collapses.
The key lesson: money is only as strong as the trust behind it. When that trust breaks, the paper becomes just paper again.
The Role of Government
In most countries, the government is responsible for money. The government:
- Prints and controls how much money exists
- Backs the currency with the strength and stability of the country
- Makes laws that require businesses to accept the national currency
- Punishes counterfeiting to keep the money supply trustworthy
This is why you see government symbols on money — it is the government saying "we promise this is real and worth what it says."
Discuss Together
What would happen if anyone could print their own money at home? Why would that be a problem? How does this connect to the idea that money is based on trust?
Check Your Understanding
1. Why is a $20 bill worth $20 even though it is just paper?
2. What is the difference between intrinsic value and assigned value?
3. What happens when people lose trust in a country's money?
4. What role does the government play in making money work?
Key Takeaways
- Money has value because of shared trust and agreement, not because of what it is made of.
- Intrinsic value comes from the thing itself; assigned value comes from what people agree it is worth.
- When trust in money breaks down, hyperinflation can make it nearly worthless.
- Governments back currency and maintain trust in the money system.
