PCGS was established in 1986 by a small group of the nation's leading rare coin experts. The intention of PCGS would be to create a climate in which consumers could participate in the coin market with greater confidence. As PCGS came up with a standard in grading coins and they would keep a record of coins graded.
PCGS pioneered the sonically-sealed, high security capsule as a method of reinforcing its Guarantee of Grade & Authenticity of each PCGS coin.
In addition, the unique certification number permanently sealed inside each coin capsule may be utilized by the coin's owner as a reliable means of identification of the coin against PCGS database.
Once the grading process is complete, the coin (with a certification tag indicating its individual identification number, denomination and grade), is sonically sealed inside a tamper-evident coin capsule. A unique certification number is then assigned from the PCGS computer inventory system. This important process enables PCGS to methodically track all coins graded by PCGS.
With this in mind we now know that PCGS as the ability to give us the Population numbers and grades of all coins found at the World Trade Center vault and they will have computer file on the coins. So now it should not be to long before we have this information.
