Avraham (Abraham) paid 400 shekels for the Me’aras Hamachpela (Cave of the Patriarchs) [Bereishis (Genesis) 23:16]. However, these were especially valuable shekels called centenaria. Each of these special shekels was worth 2,500 normal shekels [Bava Metzia 87a]. What was the value of the payment made by Avraham in normal shekels?
2,500 x 400 = 1,000,000
