How important is the coin you own? More specifically, is it one of the finest examples known? This information is of significant value because many collectors seek to own the very best coins available, and they pay big money for that privilege.
The PCGS CoinFacts Condition Census tells you how your coin ranks against other, similar examples. For instance, if you own a 1909-S V.D.B. Lincoln Cent in PCGS MS67 Red, you have one of the top nine examples (see http://www.pcgscoinfacts.com/Coin/Detail/2428). If a PCGS MS67+ Red example came onto the market, you would know instantly that it is the single best example.
The PCGS CoinFacts Condition Census lists the ten finest examples known of a particular coin. The top five in the census are listed on the specifics coin's "home page." The entire ten coin census can be viewed by clicking the "more" link at the top right of the home page census. PCGS certified coins are listed at their stated grade. Raw coins and coins certified by other companies are listed with an estimated grade. Where known, auction history or private offerings/sales are included.
