The current coin grading system is based on 70 grades. The lower numbers indicate greater wear and as those numbers get progressively higher the condition of the coin improves until 70 is reached which indicates a perfectly struck coin with no flaws, scratches or nicks. At one time it was thought that no coin could be perfect except perhaps in proof condition [called Proof 70] but in recent years the market has been awash with perfect coins proof and business strikes alike. [Business strikes are coins minted for release to the general public for daily business transactions and when considered perfect they are called MS 70.] Anyone can declare their coin to be a certain grade since grading is, after all, just the opinion of one person. However, those persons who deal with coins a great deal can become more experienced in the grading of a coin and thus their opinion is more greatly valued. The coin collecting community has seen the rise of third party grading companies who assign a grade to a coin and verify its authenticity. Many of these companies have earned the respect of many collectors. However, also on the rise are coin grading companies who do not grade properly so when selecting a grading company care must be taken and a little research made to insure you select a reputable company.
