Independent Coin Grading Services Compared

In 2002, PNG and ICTA conducted a survey of independent or professional American coin grading services.
"Responding to hobby concerns about perceived wide variances in the grading standards between different rare coin certification services, the Professional Numismatists Guild (PNG) and the Industry Council for Tangible Assets (ICTA) asked their members for their professional opinions."
Survey respondents were asked to rate seven different grading services on a ten-point scale to evaluate 11 different criteria, from grading accuracy to the quality of the holder in which certified coins were housed. The voting scale ranged from "unacceptable" at the low end to "outstanding" at the high end.
