I proudly use the top 3rd party grading companies, CGC and CBCS, to assist with signatures at shows and private events. For many years, I have been collecting and selling comics with sought-after signatures. Many times, requests come in for a signature on a specific comic book, and I have completed those requests, leaving very happy customers along the way.
When selling online, I like to use grading methods through CGC, CBCS, and CBCS RAW programs. The accuracy of grading is trusted throughout the industry. Third-party grading helps me expedite sales and keep customers happy with the condition of a comic without them seeing it in person.
