ICG
ICG (Independent Coin Graders) is a third-party grading service established in 1998. They thoroughly assess coins for authenticity and quality. While ICG is respected by many collectors, it is less widely recognized than some older, more established grading services. ICG coins can only be listed at GreatCollections with a $1 minimum bid (ie. unreserved).
