August 29, 2013 – Professional Coin Grading Service (PCGS), a leading coin authentication and grading company, introduces new and improved holders offering better security, usefulness and efficiency to house and protect PCGS-certified coins in mainland China. PCGS is not charging any additional fees for their improved, state-of-the-art holders.
Coins certified by PCGS are sonically sealed (encapsulated) in special inert plastic holders that help protect the coins from environmental damage and give buyers and sellers peace of mind that the coin inside is genuine and accurately graded. A unique certification number is permanently sealed inside each capsule.
“We now have a new generation of PCGS holder with several new security features as well as scratch resistant surfaces and superior clarity for viewing the coin inside,” said Mr. Don Willis, President of PCGS, a division of Collectors Universe, Inc. “These improved, durable plastic holders are scratch resistant and they are tamper evident to easily detect if someone has tried to open them. They will provide optimum protection for easy handling and safe, long-term storage of coins,” Mr. Willis explained.
Mr. David Hall, President of Collectors Universe, Inc. and a PCGS Co-Founder, stated: “Since 1986, PCGS experts have examined more than 26 million coins with a combined value of over US$27 billion. We have continually made improvements to provide benefits to the hobby, and we believe collectors and dealers deserve the best possible holder without having to pay additional money for it.”
