As Senior Editor of the Whitman Red Book, Jeff Garrett knows the importance of rarity in numismatics.

As the number of collectors increases, the demand for Coin Rarity or extremely rare coins increases as well. The same can be said for common issues, but the supply always seems to be large enough to meet demand. It would take a huge increase in demand for common-date Saint-Gaudens Double Eagles to make them rise in price significantly. But it would not require very many new collectors of the 1908-S Double Eagles series in MS 64 to see its prices rise. The same can be said of common-date Morgan Dollars versus rare issues.
