Eighty minae
From Epicurus Wiki
Tradition has it that Epicurus bought his Garden for eighty minae. In ancient Greece, 60 minae was equivalent to one talent, or 26kg of silver. 80 minae is thus 1-1/3 talents = 35kg = 1,234.5 ounces of silver. As of June, 2007, 1,234.5 ounces of silver @ $13.75/oz is worth nearly USD 17,000 -- a real estate bargain by modern standards, but perhaps a dear price by ancient standards.
