Kevin Boyd has been working with CGC since 2001. At first, he assisted in the development of the Signature Series program and was the company’s first Director of Signature Series – traveling to shows across North America  for the company between 2005 and early 2010, assisting customers in obtaining autographs for their collectibles. In 2010, an increased workload at his day job led to Boyd stepping down from the position, although he has continued to assist the company at some events such as C2E2 and the New York Comic Con.

Since 2005, Kevin Boyd has been an Overstreet Price Guide Adviser, and his market reports have appeared in several editions of the annual Overstreet Comic Book Price Guide.

  1. Hello, I have 1 particular comic book I was looking to grade but I’m not really sure of what the process is. Also what the cost is to grade comic books. If you could get back to me that would be great. Thanks so much.
