In this investigation, three honorable mentions (metal artifacts) of the order of Christ (cross, lady's and gentlemen's medal) were performed using Energy Dispersive X-ray Fluorescence (EDXRF) technique. This analysis were performed with a portable Amptek assemble of Si-drift XR-100SSD (25 mm2 × 500 μm) detector, equipped with a 12.5 μm Be entrance window, pre-amplifier and digital pulse multichannel processor and Ag target. Analytical parameters were 5 μA and 30 kV for 180 s at 2 mm distance to the target. Points distributed in distinct parts were analyzed in each of the metal artifact. The WinQxas software was employed for spectral analyses. These data provide to curators and historians knowledge for cataloging and subsidies for correct storage. In addition, they can be used to identify forgeries (heritage appreciation).openAccessResumo de eventos científicoshttps://orcid.org/0000-0001-7766-2692
