From a case study in a research project dedicated to the problems of Archeology of identity in an area of historic border with the city of Buenos Aires, current the San Vicente Partido, we explores the practices of donation and conservation of objects. It has been conducted the survey in the Sanvicentine Cultural Museum, located in the city of San Vicente, head of eponymous partido, of all those considered to be antiques, either by its historical or archaeological value, as well as others who are placed there as an ornaments. This survey was also complemented by documentation of diverse nature and carrying out an anthropological interview to one of the neighbors who, with a small group, takes care of the museum and its attendance sporadically. The information exposed allows us to understand some of the main characteristics of the aforementioned practices, not only in this type of museums, but also in the setting-up of private collections such as the one that gave rise to this particular museum. Finally, we discuss the implications that these objects had and still have in the construction of identities in this type of social contexts.
