The Glórias Authenticity Scale is based on a multifactorial professional analysis applied to signed items, handwritten documents, and historical memorabilia. The assessment combines graphic observation, historical consistency, market context, and available provenance, reflecting a well-founded professional opinion based on the elements presented at the time of analysis.
The methodology considers, among other factors, the general coherence of the item analyzed, the historical plausibility of the reported context, the available provenance documentation, the visual characteristics of the signatures or handwritten elements present, as well as the compatibility of the set with known examples from the period analyzed.
LEVEL G1 – NOT AUTHENTIC
The analyzed item presents graphic, visual, or contextual characteristics incompatible with known authentic examples of the purported signatory. The observed elements may correspond to mechanical reproduction, copy, autopen, or another form of non-handwritten application. This conclusion does not necessarily imply fraudulent intent on the part of the item's current owner.
LEVEL G2 – PROBABLY NOT AUTHENTIC
The analyzed item presents significant inconsistencies when compared to known authentic examples, the historical context, and the standards normally observed in the specialized market. Although some elements may remain inconclusive, the overall analysis raises significant doubts about the authenticity of the handwritten elements present in the item.
LEVEL G3 – AUTHENTICITY UNDETERMINED
The analyzed item presents some elements compatible with known authentic examples, but also limitations, ambiguities, or insufficient documentation that prevent a more certain conclusion. The analysis of handwritten elements, available provenance, and historical context remains inconclusive given the current information presented.
LEVEL G4 – AUTHENTICITY STRONGLY SUPPORTED
The analyzed item exhibits graphic, material, and contextual characteristics highly compatible with known authentic examples from the signatory's period. The analyzed set reveals strong historical coherence and presents no significant inconsistencies in light of the available elements at the time of assessment. While the analysis is particularly favorable, the absence of independent provenance documentation or complementary records may prevent an even stronger documentary support for authenticity.
LEVEL G5 – AUTHENTICITY EXCEPTIONALLY SUPPORTED
The analyzed item exhibits graphic, material, and contextual characteristics highly compatible with known authentic examples, revealing strong overall coherence among the handwritten elements, the medium, the historical context, and the available provenance. The documentation presented provides particularly solid support for the authenticity of the analyzed set, with the presence of independent elements for contextualization, record, or chain of provenance.
Methodological note
The conclusions presented reflect a specialized professional opinion based on the elements available at the time of analysis. Unless otherwise indicated, evaluations are conducted remotely based on photographs, documents, and information provided by the item's owner.
