✔ The market value assessment is free and assumes that the document is authentic, answering the question: "How much is my document worth if it is authentic?"

The authenticity study, on the other hand, is a distinct process, costing R$ 490 per document — or 10% of the market value, in the case of items valued above R$ 5,000. Payment must be made in advance on this page, via card, Pix, or bank transfer. This opinion answers the question: "Is my document authentic?"

✔ We do not have a physical office; we work remotely and evaluate your documents based on images sent to contato@glorias.com. We need UNCROPPED and SHARP images - ideally scanned - of your document to be able to perform a good analysis.

✔ We analyze each document very carefully, using our experience, the database we have built over the years, and, in some circumstances, we seek the help of other specialists. The value of the opinion is based solely on the specialist's experience and professionalism.

✔ If the document is assessed as dubious or inauthentic—that is, in cases of error in identifying authorship, reproduction, forgery, or the use of an autopen—we will issue an opinion explaining our arguments, and there will be no refund of the amount charged.

✔ The certificate delivery time is up to one week , depending on the complexity of your document and our availability.

✔ The certificate is delivered as a PDF file via email , which you can print. We keep the original certificate of authenticity to ensure permanent and irrefutable proof of the autograph's authenticity. This preserves the integrity of the certification process. If a future buyer or collector wishes to verify the authenticity of your autograph, they can contact us, and we can confirm the existence of the original.
