Confirm the authenticity of a baseball certified by History of the Base Ball by entering the certification number from its Letter of Authenticity.
Every authenticated item is assigned a unique number that accompanies a printed Letter of Authenticity.
The letter must appear on our proprietary watermarked paper and bear the live signature of expert Brandon Grunbaum.
Each record includes photographs, manufacturer, era, grades, and appraisal, so buyers and heirs can verify it at any time.
