An Ōban (大判) was a monetary ovoid gold plate, and the largest denomination of Tokugawa coinage. Tokugawa coinage worked according to a triple monetary standard, using gold, silver and bronze coins, each with their own denominations.[1]

The first Oban – Tenshō Ōban (天正大判) – were minted by the Gotō family under the orders of Hideyoshi in 1588.[2]
The Tenshō Ōban was equivalent to ten Ryōs, or ten Koban (小判) plates, with a weight of 165 g.
Notes
gollark: What if you implement gravel with a Python frontend which compiles it to bytecode and a Rust bit which interprets the bytecode?
gollark: The gravel variants.
gollark: Have you considered using multiple names?
gollark: Yes. I REGULARLY end up having `npm` warn me of a project having serious security vulnerabilities after leaving it for a month.
gollark: Why did you download 200 million NPM packages? Do you WANT suffering‽
