This FAQ covers everything you need to know about the 100 rs coin, including its legal status, features, history, and how it compares to other currencies. Whether you're a collector, a curious citizen, or a business owner, this guide provides clear, factual answers to common questions.

What is the 100 rs coin?

The 100 rs coin is a legal tender coin issued by the Reserve Bank of India (RBI), with a face value of 100 Indian rupees, and it is primarily used for commemorative purposes rather than everyday transactions.

These coins are minted by the India Government Mint and are often released to mark significant events, personalities, or anniversaries. For example, the RBI has issued 100 rs coins to honor Mahatma Gandhi, Rabindranath Tagore, and the 100th anniversary of the Taj Mahal. While they are legal tender, they are rarely seen in circulation because their metal value and collectibility usually exceed their face value.

Is the 100 rs coin legal tender?

Yes, the 100 rs coin is legal tender in India, meaning it can be used to settle any debt or transaction up to its face value.

However, in practice, businesses and individuals may be reluctant to accept it due to unfamiliarity or concerns about authenticity. According to RBI guidelines, all coins issued under the Coinage Act, 2011, including commemorative ones, are legal tender. If you need to use one for payment, you can insist, but it's advisable to carry identification or proof of authenticity to avoid disputes.

How to identify a genuine 100 rs coin?

To identify a genuine 100 rs coin, check for the RBI emblem, the denomination '100' in clear numerals, and the mint mark (a small dot, diamond, or star) that indicates the minting facility.

Genuine coins also have a distinct weight (around 35 grams) and diameter (44 mm) for the standard commemorative series. They are made of a bi-metallic combination: an outer ring of copper-nickel and an inner core of nickel-brass. Counterfeit coins often have incorrect weight, blurred details, or missing mint marks. For high-value coins, consider getting them authenticated by a professional coin dealer or using a reputable grading service.

When was the 100 rs coin first issued?

The first 100 rs coin was issued in 2010 to commemorate the 100th anniversary of the Indian Council of Medical Research (ICMR).

Since then, the RBI and the Government of India have released several 100 rs coins for various occasions, such as the 150th birth anniversary of Mahatma Gandhi (2019) and the 75th anniversary of Independence (2022). The exact dates and designs vary, and you can find a complete list on the RBI website or the India Government Mint's official site.

Can the 100 rs coin be used in vending machines or ATMs?

Most vending machines and ATMs in India are not programmed to accept 100 rs coins, so you cannot use them for automated purchases or cash withdrawals.

These machines typically accept lower-denomination coins (₹1, ₹2, ₹5, ₹10) and some newer machines may accept ₹20 coins, but the 100 rs coin is too large and uncommon. If you want to exchange it for cash, you can visit any bank branch and deposit it into your account or ask for equivalent banknotes. Banks are required to accept legal tender coins.

What is the difference between a 100 rs coin and a 100 rs banknote?

The primary difference is that the 100 rs coin is a metallic coin with a higher production cost and collectible value, while the 100 rs banknote is a paper note that is more practical for daily transactions.

Both are legal tender, but the coin is heavier, bulkier, and less convenient to carry. Additionally, coins have a longer lifespan than banknotes, which wear out quickly. From a collector's perspective, the coin may have numismatic value beyond its face value, especially if it's a limited edition or in pristine condition. The banknote, on the other hand, is widely used and readily accepted everywhere.

Why are 100 rs coins not commonly seen in circulation?

100 rs coins are not commonly seen in circulation because they are primarily minted for commemorative purposes, and people tend to keep them as collectibles rather than spend them.

Additionally, the cost of minting a 100 rs coin is higher than its face value, so the government limits its production. Retailers and the public are also less familiar with them, leading to a lack of acceptance. In many cases, these coins are sold by the RBI or India Government Mint at a premium to collectors, which further reduces their presence in everyday cash flow.

Where to buy a 100 rs coin in 2026?

You can buy a 100 rs coin from the India Government Mint's official website, the RBI's retail outlet, or authorized post offices, as well as from reputable coin dealers and online marketplaces like eBay or Amazon.

However, be cautious of counterfeits and inflated prices. Official sources sell these coins at face value or a small premium, while third-party sellers may charge significantly more due to rarity. Always verify the seller's credibility and request a certificate of authenticity for high-value purchases. For the latest availability, check the India Government Mint's website or contact them directly.

Final Thoughts

The 100 rs coin is a fascinating piece of Indian currency that serves both monetary and commemorative purposes. While it is legal tender, its real value often lies in its collectibility and historical significance.

As with any investment, it's wise to do your research and consult experts if you plan to spend significant amounts on rare editions. The 100 rs coin is more than just a piece of metal; it's a piece of history.
