Sometimes the marks you think are nicks are actually tiny flaws that were in the planchet before the coin was struck. The dies did not erase them when the coin was struck. The mark that is next to the "D" in "UNITED" on this 1880 gold dollar is an example of that. This piece is in an old green label PCGS MS-65 holder. It is P-L on both sides, which not unusual for this date because of the low mintage. To show you how lose the grading standards have gotten, NGC graded this 1885 gold dollar MS-66. The dealer from whom I purchased it, priced at a deep discount below the MS-66 number.
Just goes to show you how most buyers find the grade more appealing than the coin. These grades deserve to be swapped, pretty egregious if you ask me.
Grading services are part truth and part hype. Some servicesare all hype and no truth. When the customer gets what he or she wants, there is not much room for those who want to maintain standards to combat that.
