Buy the Best
If you are offered the finest known of a type you should acquire it. Owning it can only enhance the value of your other sets. Relative rarity matters.
Buy both Gold and Silver
Frequently we focus too much on gold coins without considering the equal or superior rate of return available in silver coinage.
Diversity
Consider the classic portfolio theory as you acquire silver, gold, type and commemorative coins. One can never predict the relative performance of each group.
Sets
Consecutive date runs in high mint state are extraordinarily effective. It is well known that the sum is often worth more than the individual parts.
The First Year
The first year of issue normally outperforms the popular dates.
Grading
Buy only graded coins. Top-name grading and eye appeal matter.
Historical Significance
A rare coin represents a tangible remnant of the past. It can be viewed as a fine piece of art that embodies the cultural and economic environment during which it was created.
Acquisition Management
There are literally millions of U.S. coins for sale at this moment. The key is profitable selections - not random acquisitions.
Cost Information
Access to all the venues (public and private) of the most comprehensive data regarding price is critical in building an appropriate portfolio.
Information Glut
It is essential to monitor the vast amounts of information about market movement and organize it into a coherent action plan for an individual portfolio.
