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.

US Mint Sales: Bullion Gold Hits 1999 Highs, Silver Eagles Breach...
The latest United States Mint sales figures are contrasting. Numismatic coins moved slower as is often the case toward the middle of the year when extended daylight hours offer collecting distractions.
But coins struck for investors amped higher, and are shooting for records. Cases in point: Gold Eagles are selling as fast as they were during the Y2K scare; Silver Eagle sales just smashed 15 million in less than five months.
More specifically, during the last week alone:
- 22-karat bullion American Gold Eagles jumped 65,500 --more than April's total, reaching 176,000 for May. Monthly sales have not been higher since August 1999.
- .999 fine bullion American Silver Eagles soared more than 1 million, hitting 3.5 million for May. They are nearing the 3,696,000 all-time monthly record set in December 1986.
- 24-karat bullion American Gold Buffalos advanced 15,500, rising to 70,500 for May.
