Certified Guaranty Company (CGC)

CGC will be offering onsite grading at Nickel City Con!

“We are thrilled that CGC has chosen to exhibit and grade on-site at Nickel City Con. CGC only grades on-site at a handful of shows each year, and for them to choose to do so at Nickel City Con is both an honor and a testament to how our show is quickly establishing itself as a must attend on the con circuit,” said Adam Martin, Dave & Adam’s CEO.

Founded in 1999, Certified Guaranty Company is the first independent, impartial expert third-party grading service for comic books, magazines, lobby cards and photographs. CGC offers expert condition analysis, including thorough restoration detection, before grading and encapsulating collectibles in state-of-the-art, archival-safe holders. CGC does not buy or sell collectibles — it is committed to providing an independent opinion that collectors and dealers can always trust, so they can buy and sell with confidence.
