Email Opinion

An informal opinion via email based on a large, clear photograph. Email Opinions indicate whether the item will “likely pass” or “likely fail” my full authentication process. This may detect forgeries, Autopens, secretarials or if an item may be authentic. It may be impossible to determine through a photo if an item is a copy or a printed autograph. My opinion is offered under the presumption the item is not a copy of an authentic autograph.

Email Opinions begin at $12, and there is a discount for multiple items.

How to obtain an Email Opinion…

Letter of Authenticity (LOA)

Letter of Authenticity with tamper-EVIDENT hologram and embossed seal on Heavy archival paper.

Comprehensive Examination

For a Letter of Authenticity (LOA), you must submit the item(s) for a comprehensive in-hand review.

I will analyze the signature formation, application, ink and other factors against my database of thousands of verified authentic examples. I will examine the item under high magnification using a ProScope digital microscope when necessary.

Certification

When I determine an item is authentic, I will issue a Letter of Authenticity that features a high-resolution photograph, a tamper evident hologram and an embossed seal.

I do not place stickers on items. Because I only issue Letters of Authenticity that feature a large, clear image of the signature, there is no need to sticker an item.
