You’re looking at a 100-dong note. It’s small, brown, and frankly, feels a bit like play money. If you try to convert 100 dong to usd, you’ll quickly realize that the math is almost comical.
As of early 2026, the exchange rate is roughly $0.000038.
Yeah, you read that right. You would need over 26,000 of these little notes just to get a single American dollar. In a world where a cup of coffee in Hanoi now sets you back about 35,000 VND, the 100-dong note is basically a ghost in the machine. But here's the thing: while it might not buy you a grain of rice, this tiny denomination carries a weight that the exchange rate doesn't show.
The Reality of 100 dong to usd Today
Let’s be honest. If you drop a 100-dong note on a busy street in Ho Chi Minh City, nobody is stopping to pick it up. Most modern Vietnamese citizens haven't seen one in their wallets for years.
The State Bank of Vietnam (SBV) hasn't technically "retired" it, but they stopped printing them ages ago. Why? Because the cost of the paper and ink is worth way more than the note itself. It's a classic case of inflation outstripping utility.

Even the 200 and 500-dong notes are rare now. You might see them as change in a supermarket where every last digit counts, but even there, most clerks will just round your total or give you a piece of candy instead of a handful of paper that's practically worthless.
When you look at 100 dong to usd, you're seeing the extreme end of a "frontier market" currency. Vietnam's economy is booming—GDP growth is projected at 7.6% for 2026—but the currency still carries the legacy of decades of devaluation and hyperinflation from the 80s and 90s.
What Can You Actually Do With 100 Dong?
Honestly? Not much.
- Buying stuff: Zero. Nothing costs 100 dong. Even a plastic bag at a local market is 1,000 or 2,000 dong.
- Tipping: Don't do it. It’s actually kinda insulting to tip someone with a 100-dong note. It’s like giving someone a single penny in the US, but 300 times less valuable.
- Collecting: This is where the value lives. Because they aren't in circulation, they've become souvenirs.
Why the Exchange Rate is So High
You might wonder why the government doesn't just lop off a few zeros. It's called "redenomination," and it's a massive headache. If Vietnam changed the currency so that 1 "New Dong" equaled 10,000 "Old Dong," they'd have to reprint every single note in the country.

The SBV prefers stability over vanity. In 2026, their focus is on a 15% credit growth target and keeping the macroeconomy steady. They’d rather have a currency with lots of zeros that stays predictable than a "pretty" currency that causes a panic during a transition.
Managing the 100 dong to usd relationship is actually a point of pride for the central bank lately. While the Dong has weakened slightly against the Dollar—heading toward a projected 26,650 VND per $1 by the end of the year—it hasn't spiraled.
The Survival of the Paper Note
The 100-dong note is made of cotton paper. If you've handled the higher denominations like the 500,000 VND, you’ll notice they feel like plastic. That’s polymer.
Vietnam switched to polymer for anything 10,000 VND and above to stop counterfeiting and make the money last longer in the humid tropical heat. The 100-dong note was left behind in the "paper era." It’s a relic of a different Vietnam, one that wasn't a global tech and manufacturing hub.

Practical Advice for Dealing with Dong
If you’re traveling or doing business, forget the 100-dong conversion. It’s a rounding error.
Instead, focus on the "thousand" rule. When a local says a price is "fifty," they mean 50,000 VND. They almost always drop the last three zeros in conversation. It makes the math way easier.
- Check your notes carefully: The 20,000 VND and 500,000 VND notes are both blue. In a dark taxi or a crowded market, it's incredibly easy to hand over $20 when you meant to hand over 80 cents.
- Avoid the coins: Vietnam minted coins in the early 2000s (200, 500, 1000, 2000, and 5000 denominations). They were a disaster. People hated them, they didn't work in vending machines, and they basically disappeared from use by 2011. If someone gives you a coin, keep it as a lucky charm, because you won't be able to spend it.
- Use the "100k" benchmark: Think of 100,000 VND as roughly $3.80. This is your baseline. A good bowl of Pho is about 40,000 to 60,000 VND. A high-end cocktail in District 1 might be 250,000 VND.
The 100 dong to usd rate tells a story of a country that has grown faster than its currency denominations could keep up with. It's a quirk of history. While the note itself is functionally useless for commerce, it's a reminder of how far the Vietnamese economy has come from the days when 100 dong actually meant something.
To stay ahead of currency fluctuations, always use a real-time mid-market rate tool before exchanging large sums at gold shops or banks in Hanoi or Ho Chi Minh City. Avoid airport exchanges whenever possible, as their spreads can eat up to 10% of your value. Stick to reputable banks like Vietcombank or authorized jewelry stores in the city centers for the most accurate rates.
