- Lucas: So if you've been stepping into history with us episode by episode through the Chola Empire, you've heard about the temples, the waterworks, the navy, the guilds. But there's something that ties all of that together, something that literally made the empire run: money. Lucas: I mean actual coins. Under Rajaraja Chola I, the empire minted one of the most recognisable gold coins of the medieval world. It's called the RajaRaja Chola coin — on one side you have the king standing under a lamp, on the other a seated goddess, probably Thirumagal or Lakshmi. And that design became a kind of brand. Luna: A brand? Like people trusted it across borders? Lucas: Exactly. These coins have been found in Sri Lanka, in Sumatra, even in southern Thailand. The Chola didn't just conquer territory — they created a currency zone. And it's not just gold. They minted silver and copper too, but the gold coin was the prestige item. Lucas: The mint was likely in Thanjavur itself, near the Brihadeeswarar temple. The process was pretty sophisticated: they'd melt gold, alloy it with a bit of copper to harden it, then hammer-strike the dies. The weight was standardised — around 4.2 grams for the gold coin, which was called a 'kasu' in Tamil. Luna: So it's like a medieval gold standard. Lucas: In a way, yes. But what's really interesting is how these coins changed the local economy. Before Rajaraja, a lot of trade in Tamil country was still barter — paddy, cloth, cattle. But the Chola administration started demanding taxes in cash, especially the 'Valanci' tax. Luna: Valanci — I've seen that word in temple inscriptions. Lucas: Right. The Valanci was a levy on merchants, paid in gold. It's mentioned in dozens of inscriptions from the Brihadeeswarar temple and others. The tax was collected by local assemblies — the sabha — and used to fund temple rituals, irrigation repairs, even famine relief. Lucas: And the coins weren't just for big trade. You'd have smaller denominations for everyday purchases — a measure of rice, a pot of oil. The Ayyavole and Manigramam merchant guilds, which we talked about in earlier episodes, used these coins to settle accounts across the Indian Ocean. Luna: So the coinage is really the backbone of the whole economic system. Lucas: Absolutely. And there's a darker side too. By the late 12th century, under later Cholas like Kulothunga III, the gold content started to drop. They were debasing the currency — mixing in more copper — to stretch the treasury. That caused inflation and probably undermined trust. Lucas: There's an inscription from Tiruvidaimarudur that complains about counterfeit coins. The temple authorities actually set up a system to test coins by weight and sound — they'd drop them on a stone and listen for the ring. Pure gold has a distinct tone. Luna: That's amazing. So they had quality control. Lucas: They did. And it ties into something bigger: the Chola state was remarkably literate and bureaucratic. They recorded everything — tax rates, coin types, even the names of mint officials. We have copper-plate grants that specify exactly how many coins were donated to a temple. Lucas: Now, a quick honest thing — episodes like this, where we dig into specifics like coinage and tax records, they take a lot of research time. And this show is entirely listener-funded, no ads. A handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds making this many of these. Luna: Yeah, it's a small community but it keeps the whole thing going. Lucas: It really does. So back to the coins — one of the most dramatic finds came in 1996, when a hoard of over 1,000 Chola gold coins was unearthed in a pot near the Brihadeeswarar temple. They'd been buried during the Pandya invasions, probably by a merchant who never came back. Luna: That must have been incredible to discover. Lucas: It gave numismatists a treasure trove of data. They could trace the evolution of the design over decades — the king's posture changes slightly, the goddess's hand position shifts. Each die was hand-engraved, so no two coins are exactly identical, but the style is consistent. Lucas: And the coins tell a story of the Chola decline too. The later coins are cruder, less gold. By the time the Pandyas and then Malik Kafur's raids hit in the early 1300s, the mint probably stopped altogether. The empire's last coins are a shadow of Rajaraja's. Luna: So the coins are like a biography of the empire. Lucas: Exactly. They start brilliant, full of gold and artistry, then slowly get thinner and uglier as the empire struggles. But for about two centuries, a Chola gold coin was the most trusted currency from the Kaveri to the Mekong.
