I've got some really nice coins graded via NTC which Unfortunately is an inferior coin grading company. Example: if my MORGAN 1891-O MS66 is graded by NTC, this coin graded via PCGS would probably be graded as a MS64 and worth 85% less. Here's a website: http://www.bestcoin.com/Rating-Coin-Grading-Services.htm#Third Party Grading Services[h=1]Third Party Grading Services Explained[/h]which will give you a better idea about the coin grading services.
