Craig Miller has been passionate about trading cards and collectibles since childhood. Growing up in a local card shop in Southern California, he developed a lifelong appreciation for collecting, buying, selling, and trading cards and collectables.

After a career in semi-professional and arena football, Craig turned his creativity into a successful graphic design, multimedia, and printing business. He later partnered with longtime friend of more than 25 years, Shawn Denmark, to co-found Mint Authentication, combining their shared passion for the hobby with a commitment to serving collectors.

Craig continues to expand his expertise through studies in forensic handwriting examination and signature verification, bringing knowledge, integrity, and attention to detail to every autograph evaluated.

His vision for Mint Authentication is simple: provide collectors with affordable, consistent, and trusted grading and authentication services while helping preserve and grow the hobby for generations to come.
