Customers who fail to complete a purchase after an offer has been accepted will lose their ability to make future offers.

Any price discount resulting from this process cannot be combined with other discounts or promotions on our site and will constitute the final price for the item. Items remain available at the regular listed price to all users until purchased. Therefore, we suggest that users check their emails frequently for our response, as the purchase of an item is subject to its availability. Under certain circumstances, offers may be cancelled prior to the offer expiration date, and users may not always be notified of a change in offer status.

Each hand-signed document has been authenticated and is accompanied by a Certificate of Authenticity (COA) issued by our parent company, Gallery of History, Inc. The term of the COA is 10 years from the date of purchase and is valid for the original purchaser only. We have an outstanding reputation for the thoroughness of our research, our business integrity, and our service to clients. We financially stand behind our COA, which is one of the main reasons we’ve remained in business since 1981.

Within the 10-year COA period, each hand-signed item is guaranteed to pass PSA/DNA or JSA authentication, or we will refund your full purchase price.
