Numismatic Certification Institute (NCI). Dallas, TX. Established in 1985, and an affiliate of Heritage Capital Corporation. Currently not active. Grading standards are constant, based on standards set by ANACS prior to 1985, which is the year industry grading standards changed. Prices reported once a month in a supplement to CCDN.

International Numismatic Society (INS). Washington DC. One of the older grading services. Not highly regarded in dealer and collector market places. Grading is viewed as rather liberal and sometimes inconsistent. Prices reported monthly in supplement to CCDN.

There were many others, such as CompuGrade, Exactagrade and AccuGrade. However, prices have not been established for such graded coins, and the investor is well advised to avoid these coins. Many telemarketers sell coins that have been graded by these services but price them according to the PCGS values in the CCDN. This is improper and deceptive according to the Federal Trade Commission. 

The main point for you, the financial advisor is simply this. Advise your clients to purchase coins that are graded by either PCGS or NGC. This will provide your client with the most accepted and therefore most liquid form of this investment asset.
