PCGS announced that it has a process in development which will detect any foreign substance on a coin's surface, and also announced a major lawsuit filed against alleged coin doctors.
According to PCGS officials, in conjunction with the development of coin recognition technology launched in March of this year, PCGS has been developing a process to detect foreign materials and other enhancements to a coin's surfaces.
