I propose a reflection on the notion of Mapuche archive focusing on Mapuche jewelry as a special kind of document. As they were made with coins, I analyze the problem of the value associated with these jewels. Thus, I describe a historical movement, through which the coins were first withdrawn from the logic given by the Chilean political-economic archive, and then were inserted in a Mapuche logic of value and archive, understanding the latter as an instrument of political legitimacy. Then (...) I analyze their post-conquest journey, and their reinsertion in the Chilean field as commodities until their current museographic resignifications. I conclude by commenting some forms of their present assessment in the context of multicultural and patrimonial management of cultural differences. (shrink)
