✔ The credibility of a certificate of authenticity depends directly on the reputation of the issuer—built on expertise, experience, and work ethic. Our reputation is solid, the review of your document is rigorous, and the report issued is detailed ; therefore, this service is charged.

✔ Our service consists of carefully studying an autograph document to issue a technical opinion on its authenticity. This analysis takes into account verifiable information regarding provenance, handwriting, content, paper type, and other more subjective elements , such as our informed intuition.

✔ The opinion can be negative (when the autograph appears to be fake, a copy, or a print), positive (when there is no doubt as to its authenticity), or partially positive (when there is some doubt, even minimal, especially in the absence of good provenance). Regardless of the result, each opinion requires time, study, and responsibility—therefore, the fee charged is non-refundable .

✔ The subscription fee is R$ 490 — or 10% of the market value for items valued above R$ 5,000 . Payment must be made in advance on this page via credit card, Pix, or bank transfer.

✔ We don't have a physical store; we work remotely and evaluate your documents based on the images you send to contato@glorias.com. We need clear, uncropped images—ideally scanned—of your document to perform a proper analysis.

✔ The delivery time for the certificate is 2 to 5 business days . depending on the complexity of your document and our availability.

✔ The report is delivered in PDF format via email and can be printed by the client. We keep the original report archived, guaranteeing permanent and unalterable proof of our analysis. Should a prospective buyer or collector wish to acquire the autograph, they may contact us, and we will be able to confirm the existence of the original report or clarify any doubts.

✔ We are available to send you a sample report should you wish to assess the quality of our work.
