This week, the Professional Coin Grading Service announced �The Big One,� a service called PCGS Secure Plus.� A new service line that will be an option for most collectors except for rare and ultra rare coins which must be certified by PCGS Secure Plus. The significant part of this service is that PCGS is adding modern computer imaging to coin grading.

Coins grade through Secure Plus will be scanned by an optical device that will map the surface of the coin creating a digital signature of its characteristics that can be used for later reference. The digital signature is a unique identification of the coin that can withstand potential coin doctoring and to prevent the users from removing the coin from the slab to try to have it graded higher. It can also be used to determine if the coin was doctored from its previous submission such as being artificially toned.

During the announcement PCGS President David Hall (videos Part 1 Part 2) said that this should end �gradeflation� as well as work out errors in the population reports when people submit coins multiple times. Hall said that multiple submissions did not serve the industry and hope that this would end the practice. Hall noted �We did not start PCGS to grade a coin 40 times.�

Hall said that PCGS has been working on this service for two years with �industry leaders� who were not mentioned. However, in the follow up presentation by PCGS CEO Don Willis (videos Part 3 and Part 4), his technical explanation included an image of the CoinSecure, Inc. to use the CP16 CoinAnalyzer. During his part of the announcement, Willis said that the process is being patented.

Having been an advocate for computer based grading, this is a great start to using technology to assist in grading. Add the ability to digitally fingerprint the coin to prevent coin doctoring and crackout artists from resubmitting the coins multiple times hoping for better grades, PCGS has created �The Big One� in the world of third party grading.
