- Lucas: So, we've talked a lot about Chola temples, trade guilds, even their police system. But there's one thing that ties a lot of it together and we haven't touched on yet: their coins. Luna: Oh, I was wondering when we'd get to that. Lucas: Right? Coins are almost like little metal documents. And for the Chola, especially under Rajaraja I and his son Rajendra, coinage became a deliberate statement of power. They weren't just using whatever old Roman or Arab coins happened to be floating around — they minted their own, in silver and gold, with very specific designs. Lucas: The most common Chola coin you'll hear about is the kasu — that's the Tamil word for a coin, but specifically a small gold or silver piece. And then there's the fanam, which was a tiny gold coin used in everyday transactions. But what's really interesting is how these coins were designed. Luna: What did they look like? Lucas: On one side, you'd often see a standing king, sometimes under a lamp or a canopy — a symbol of royal presence. On the other side, you'd have the Chola emblem: a tiger sitting, with a bow and a couple of fish around it. That tiger was the Chola royal insignia, and it was instantly recognizable across the Indian Ocean. Lucas: But here's the clever part: the legends on the coins were usually in both Tamil and Sanskrit. Tamil for the local population, Sanskrit for the broader cosmopolitan trade network. So a coin might say 'Sri Rajaraja' in Sanskrit on one side and 'Rajarajan' in Tamil on the other. It's bilingual branding. Luna: So they were marketing to different audiences at the same time. Lucas: Exactly. And it worked. Chola coins have been found in Sri Lanka, in Sumatra, in Java, even in China. They became a sort of trusted currency in the Indian Ocean trade, alongside the Arab dinar and the Chinese cash. The Ayyavole guild, those big merchant associations we talked about, they probably helped spread these coins. Lucas: Now, the weight system of these coins is also revealing. The silver kasu weighed about 3.4 grams, which is very close to the Roman denarius and the later Arab dirham. That wasn't an accident. The Chola wanted their coins to fit into existing trade networks, so they matched the weight standards. Luna: So it's like they were making a coin that could be used anywhere. Lucas: Yes, but with their own stamp. And they controlled the supply tightly. We have records from temple inscriptions showing that the king would donate specific amounts of gold or silver to the temple, and the temple would then have coins minted locally, often under royal supervision. The Thanjavur temple alone probably had its own mint. Luna: Was there any controversy over the purity of the coins? Lucas: Great question. Later in the Chola period, especially under Kulottunga I, there's evidence of debasement — mixing copper with silver to stretch the supply. That caused inflation and probably some loss of trust. But during the peak under Rajaraja and Rajendra, the coins were high purity. We know this because hoards have been analyzed. Lucas: One famous hoard was found in Thanjavur itself — a pot full of silver kasu from the 11th century. When they tested them, the silver content was over 90 percent. That's serious quality control. Luna: That's better than some modern coins. Lucas: Honestly, if that little fact was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. We keep this show ad-free, and it's listeners like you who make that possible. Luna: Yeah, it's a small thing that really helps us keep going. Lucas: So, back to the coins: the designs weren't just static. Under Rajendra I, after his famous Ganges campaign, he issued a new coin type that showed a figure holding a bow in one hand and a lotus in the other — maybe symbolizing his conquest of the north and his piety. And later, under the Later Cholas, you start seeing more Shaiva symbols, like the trident or the bull. Luna: So the coins were like a visual chronicle of the empire's priorities. Lucas: Exactly. And they weren't just for trade. A huge number of coins were used for temple offerings. The inscriptions at the Brihadeeswarar temple record massive donations of kasu to the temple treasury. Those coins were then probably melted down and reminted, or used to pay temple staff and artisans. So there was a circular economy. Lucas: There's also a fascinating debate among historians about whether the Chola ever had a true 'monetary economy' or whether most transactions were still barter, especially in the villages. The evidence from the Uttaramerur inscriptions suggests that taxes were often paid in kind — rice, oil, cloth — but fines and temple donations were often specified in cash. Luna: So coins were for specific purposes, not everyday shopping. Lucas: Probably. But in the big trade ports like Nagapattinam or Kaveripattinam, coins were certainly used for buying and selling goods from across the ocean. The Chola even issued copper coins for small change, though those are rarer archaeologically. Lucas: One of the most interesting things about Chola numismatics is that we have very few coins with portraits. Unlike Roman or Greek coins, which often had a realistic profile of the emperor, Chola coins were more symbolic. The king is shown as a generic standing figure, not a specific likeness. That might be because of local artistic conventions, or maybe because the focus was on the office, not the individual. Luna: It's almost like a logo, not a photograph. Lucas: Right. And that logo — the tiger, the standing king — was recognized from the shores of Sri Lanka to the ports of Sumatra. When Srivijayan merchants paid their dues in the Strait of Malacca, they might have used Chola coins. That's how integrated the economy was. Lucas: We even have a Chinese account from the 13th century mentioning that in Quanzhou, they found 'foreign silver coins from the country of Zhu-nian' — which likely refers to the Chola. So the coins traveled that far. Luna: I wonder if there's a map of where Chola coins have been found. Lucas: There is, actually. Historians have plotted the find spots, and they cluster along the Coromandel Coast, across Sri Lanka, and then a trail down the Malay Peninsula to Sumatra. That matches exactly the trade routes we talked about in earlier episodes. The coins are like breadcrumbs of the Chola maritime network. Lucas: And the minting process itself was quite advanced. They used a die-striking technique where a heated blank of metal was placed between two engraved dies and struck with a hammer. That gave a crisp image on both sides. Some coins even show a 'spade' or 'punch' mark from the process. Luna: Was the technology imported? Lucas: Probably evolved locally. The Chola had been making coins since at least the Sangam period, but those earlier ones were just punch-marked — irregular blobs of metal with a few symbols. Under Rajaraja, they standardized the size, weight, and design. That's a big leap in administrative capacity. Lucas: Now, there's one more layer: the Chola also issued what are called 'double' or 'triple' fanams — larger gold coins. Those were probably used for high-value transactions or as gifts. Some are so thin and delicate that they might have been ceremonial rather than practical. Luna: So some coins were like medals. Lucas: Exactly. The line between coin and medallion was blurry. When a king wanted to commemorate a victory, he might issue a special coin type that was then distributed to temples and nobles. That's both propaganda and piety. Lucas: And speaking of temples, the Chola also used 'temple tokens' — small metal pieces that had no official value but were used as offerings. Some of those have been found in hoards alongside real coins, which confuses the record. Luna: So when archaeologists find a hoard, they have to figure out what's money and what's not. Lucas: Right. And sometimes the hoards tell us about crises. For example, there's a hoard from the 13th century that was buried in a hurry—coins scattered, no pot—which might reflect the Pandya invasions at the end of the Chola period. People hid their savings and never came back. Lucas: So coins give us economic history, political history, and even moments of personal drama. All from a little disc of metal. Luna: It puts a human face on the empire. Lucas: Yeah, exactly. Next time, maybe we'll look at the other side of the coin — literally — and talk about what the Chola imported in return for all that silver.
