Here at Group Authentics, we use many stateside and worldwide authentication companies listed below for specialized service when we receive memorabilia attained without our being present at signing. When ever we attain a picture or movie of the autograph signing, we include them with our C.O.A. or our auditors C.O.A's listed below.

 Our 'guaranteed for life' pledge is shared with the companies we have listed and is backed by us. A Certificate of Authenticity with a numbered sticker emblem or tamper proof ink mark will be on back of most photographs, art posters and prints. With other articles like post cards, clothing, athletic equipment or you name it, they will be accompanied by a C.O.A. letter.
