Additional Slabbers:

74. ACCS (Ancient Coin Certification Service) ? - Date
75. COINLAND although it may have been removed from the list because it has never issued production slabs, just samples.
76. EAC (Early American Coppers) service lasted from 1984 - 85
77. INC (Independant Numismatic Certification) Late 2002, not sure if it is still active.
78. NIC (Company name not known) specimen found in Nov 2002 but at this time I don't know anything about the company.
79. PNG (Professional Numismatists Guild) Issued certificates 1970 - at least 1984
80. RCGS (Rare Currency Grading Service) June 2002 - Date?
81. S&G (S & G Rare coins) Late 2002 - Date (This was the first of what will become quite a problem for listing the services. It was the first company to begin using ACG's encapsulation service. Under that service the company does the grading and ACG provides the encapsulation with custom labels. By removing the considerable investment required to purchase the dies and sonic welder it allows anyone to form their own service very cheaply. At last report there are at least 14 companies that are using this service or have used it. So far I have only seen two others Rich Stiles, and CCC (Coins, Cards, and Currency). S&G was the first but CCC is the most prolific having produced at least a couple thousand slabs so far.
82. SGS (Star Grading Service) Early 2003 - Date
83. TMM (The Merick Mint) Late 2002 - Date. So far the only thing I have seen in production slabs from this company have been 1 oz US gold eagles. They also produce a novelty slab with a colorized quarter.
