✔ 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 deadline for delivery of the certificate is 2 business days . depending on the complexity of your document and our availability.

✔ The report is delivered in PDF format via email , which you can print. We retain the original certificate of authenticity to guarantee permanent and unalterable proof of the autograph's authenticity. This preserves the integrity of the certification process. If a prospective buyer or collector wishes to verify the authenticity of your autograph, they can contact us, and we can confirm the existence of the original.
