The aim of this paper is to present an overview of the uses of the gold metal in Gaul between the 3rd and 1st c. BC based on the coins and ornaments. Both are manufactured items which can also give a picture of the available precious metal. After remembering the context of the emergence of the gold coin in Gaul at the beginning of the 3rd c. BC, several points will be tackled to understand the economy of the gold: - The fineness of the coins compared to the gold content of the ornaments taking into account the function of each one (coins are serial production under the responsibility of an issuing authority and they are indicative of monetary production policies whereas it is not be the case for the ornaments) and the constraints to manufacture both these objects. The fineness of coins decreases between the 3rd and 1st c. from c. 98% to 50% or less and this phenomenon can be observed throughout Celtic and Belgic Gaul. Several hypotheses can be given to explain this decrease. It will be instructive to compare this monetary phenomenon with the composition of gold ornaments for a same chronological period and in a same area. It will then be necessary to wonder about the masses of gold used to make jewellery between the 3rd and 1st c. BC. That raises the questions of the uses of the gold metal and of the gold resources in Gaul (are there enough gold available or not ?). - The "provenance" of the precious metal studied with the trace elements contents. In this perspective, the question of the remelting must be asked. The circulation of coins at various scales but also that of ornaments as deduced from archaeological discoveries and from written sources (for instance Tite-Live points out transfers of gold between Romans and Gauls in 2nd c. BC: jewellery, coins...) will have to be considered.
