Cornerstone Numismatics - Nice coin.
Most Satin Finish coins from the year 2005-20010 are very well struck. The 2006-P Satin Finish is no exception. Most examples appear to grade about SP66 to SP68. Examples grading SP69 or higher are much scarcer. Perfect SP70 examples are almost unheard of but with enough searching, collectors may be fortunate enough to find one.
