Your Guide to Exchanging 100 Yen Currency Coins

Posted by: Ian Stainton18 Feb 2026

Just got back from Japan? If your pockets are jingling with leftover 100 yen currency, you’ve come to the right place. This guide will walk you through everything you need to know about this iconic coin and show you how to easily convert your leftover yen into pounds with our fast, easy, hassle-free, and 100% guaranteed service. With no need to sort coins, it couldn't be simpler.

Unlocking the Value in Your Leftover 100 Yen Currency

It’s a familiar story: you have an incredible trip, and you come home with a pocketful of foreign money. Maybe you're looking at a handful of those shiny 100 yen coins right now – lightweight, with their distinctive copper-nickel feel and the beautiful cherry blossom design.

Here in the UK, where we love to travel, Brits bring back billions in leftover foreign currency every year. A huge chunk of that is Japanese yen, including the ever-present 100 yen coin (currently worth about £0.47 each). Our fast and easy service is designed to turn that leftover holiday money back into cash or donate it to a good cause. You can find more interesting stats on currency in circulation over on Statista.com.

Why Bother Exchanging Your Foreign Coins and Notes?

Letting that pile of leftover foreign currency sit in a drawer is like leaving money on the table. A single 100 yen coin might not seem like much, but when you add it all up, it can quickly become a surprising amount. This isn't just true for individuals; it's a big deal for businesses and charities, too.

We are trusted by major brands, including charities, supermarkets, airports, and even police forces, to exchange foreign coins and notes they collect. The best part? There's absolutely no need to sort them. We handle everything. Our whole process is designed to be completely hassle-free, turning that forgotten holiday money into real, tangible value.

Whether you want to exchange foreign coins for yourself or donate them to charity, the goal is the same: to make sure that money doesn't go to waste. We provide a straightforward, 100% guaranteed path to doing just that.

Our trusted service gives you a reliable way to manage all your leftover foreign currency. We help you:

  • Convert foreign coins and banknotes without the headache of sorting them yourself.

  • Receive your payment quickly and securely.

By choosing to exchange your 100 yen currency and other foreign money, you’re making a smart financial decision. It’s a fast, easy step that effortlessly recovers value you thought was lost.

A Closer Look at the 100 Yen Coin

More than just pocket change, the 100 yen coin is a little piece of Japanese culture you can hold in your hand. You’ll probably notice its distinct, solid feel straight away. Made from a durable copper-nickel alloy, it has a standard weight of 4.8 grams and a diameter of 22.6 mm, making it instantly recognisable among other coins.

But the real story is in the design. On one side (the reverse), you'll find a beautifully detailed engraving of sakura, or cherry blossoms. These flowers are a huge part of Japanese culture, symbolising the beauty and fleeting nature of life. Flip it over, and the obverse clearly shows the value ‘100’ and the year it was minted.

To give you a quick reference, here are the coin's main characteristics.

Key Features of the 100 Yen Coin

Feature Description
Value 100 Japanese Yen (JPY)
Material Copper-nickel alloy (75% copper, 25% nickel)
Weight 4.8 grams
Diameter 22.6 mm
Edge Reeded (grooved)
Obverse Design Value '100', year of issue
Reverse Design Sakura (cherry blossoms)

These features have remained consistent since the coin's introduction, making it a familiar sight for anyone who has handled Japanese currency.

Decoding the Dates on Your Coins

One of the most interesting things about the 100 yen currency is how the dates are marked. Instead of using the Western calendar we're used to, Japanese coins are dated according to the reign of the current emperor. This means your coins could be from one of three recent eras:

  • Shōwa (昭和): The reign of Emperor Hirohito (ended in 1989)
  • Heisei (平成): The reign of Emperor Akihito (1989–2019)
  • Reiwa (令和): The current reign of Emperor Naruhito (2019–present)

Each coin tells a tiny part of Japan's modern history. While most are common, certain years had a much lower mintage, which can make them more interesting to collectors. For a deeper dive into specific issues, you can learn more about the 100 Japanese Yen coin first issued in 1967 in our dedicated guide.

The journey of your leftover currency is pretty simple, from sitting in your travel bag to providing real value back here at home.

As you can see, the lifecycle of foreign coins is straightforward—from being collected on a trip to being converted without any fuss.

Face Value vs Collectible Value

It's really important to know the difference between a coin's face value and its potential collectible value. For almost all the 100 yen coins you bring back from a trip, their worth is simply based on the current exchange rate. It’s only a tiny handful of coins from specific, low-production years that are sought after by collectors.

The 100 yen coin is the workhorse of everyday transactions in Japan. But back here in Britain, it often just sits in a drawer, representing untapped potential for travellers, charities, and businesses. For UK holders, this leftover currency can be easily converted. Even a small handful can add up—for instance, 100 yen is currently worth around £0.47.

For most people, the quickest and most practical way to get value from leftover currency is through a straightforward exchange service. Our process is designed to be fast, easy, and hassle-free, and you don’t need to worry about sorting through your coins to find rare dates yourself. We handle all of that for you.

How to Exchange Your 100 Yen Coins for Cash

So, you're ready to turn that pile of 100 yen currency into actual money you can spend? We've designed our service to be fast, easy, and completely hassle-free. It's a three-step process we've refined over the years to take all the stress out of exchanging foreign coins and notes.

A diagram illustrates a three-step process: weighing currency for a quote, packing items, and receiving payment.

This whole flow is 100% guaranteed, giving you total peace of mind. We're trusted by some of the UK’s biggest brands, including major charities, supermarkets, airports, and even police forces. They all rely on us to handle their foreign currency collections securely and efficiently.

Step 1: Get a Quote

First things first, let's find out what your currency is worth. Forget about the tedious job of sorting and counting every last coin; our unique system makes it incredibly simple.

  • No Sorting Needed: Just scoop up all your leftover foreign currency. It doesn't matter if it's 100 yen coins mixed with other Japanese currency, old banknotes, or even pre-euro money.
  • Weigh and Go: Pop the whole lot onto your kitchen scales.
  • Instant Valuation: Type the weight into our online currency calculator, and you'll get an instant quote based on the day's exchange rates.

This way, you know exactly what to expect before you even think about sending anything to us. No surprises, just fast and easy service.

Step 2: Pack and Post

Happy with the quote? Great. Now, you just need to get the currency to us. We’ve made this part as painless as possible.

All you have to do is pack your coins and notes securely—a padded envelope for small amounts or a sturdy box for heavier collections works perfectly. Then, just post it to our processing centre. That's it. Your part is done.

This hands-off approach is what our hassle-free service is all about, saving you a huge amount of time and effort. If you're curious, you can read our full guide on how we make coin conversion to cash so simple.

The 100 yen coin has been a fixture in Japan since 1967, and the country remains a very cash-heavy society. To give you an idea, a staggering 128.8 trillion yen was in circulation as of early 2024. This creates a real opportunity, as currency values are always on the move.

For instance, a collection of 10,000 x 100 yen coins (worth ¥1 million) could have jumped in value by 6% in just a few months thanks to favourable exchange rate shifts. It just goes to show how quickly leftover currency can appreciate. You can dig into more stats like this over at the Bank of England's banknote statistics page.
