The card forming a support for a valuable object, particularly a small precious metal ingot incorporated in said card, includes a core with a through aperture in which said valuable object is arranged, said through aperture having larger dimensions than those defined by the contour of said valuable object in the main geometric plane of said card. This valuable object is located in a central area of the through aperture so that a transparent peripheral area surrounds the valuable object inside said through aperture. The valuable object is embedded in a transparent resin which entirely fills the area peripheral to said valuable object between said object and the contour of the through aperture, so that the space remaining in the aperture around the valuable object is entirely filled by the resin.
