Email Opinion

An informal opinion via email based on a large, clear photograph. This may be effective for determining forgeries, Autopens, secretarials or if an item may be authentic. Note that it may be impossible to determine through a photo if an item is a copy or a pre-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.
