Over the course of more than 50 years, the sale of gold bullion coins to private collectors developed into a multi-billion dollar business. The Bank of Nova Scotia began selling gold coins into the U.S. market at the beginning, so the force came from elsewhere.

The Bank of Nova Scotia made the first organized effort to sell wholesale quantities of foreign gold coins to American investors and collectors when it began offering so-called "bullion" or semi-bullion coins into the U.S. market at the beginning of the 1960s. Since these coins were generally considered to be "rare and unusual," they were granted entry because they offered price lists that were out of the ordinary and demanded a small premium.
The United States quarter eagle ($2.50), half eagle ($5), eagle ($10), and double eagle ($20) gold pieces were the only items on the initial list in January 1961. Also included were the British sovereign and half-sovereign, as well as the Swiss 20-Preseli. Wafers weighing 25, 50, and 100 grams were also on the list, but they could not be brought into the United States.

The Dominican Republic's 30-peso, the 20-franc "Napoleon" of France, the 10-franc piece, and the heavy 1.2-ounce Mexican 50 pesos were added by the Bank of Nova Scotia on July 5, 1961. Price list 32 (March 28, 1962), nearly a year later, made the distinction between old sovereigns and new sovereigns and included a footnote stating that coins minted after 1933 could not be legally imported into the United States.
This also applied to Austrian restrikes from 1915 that were 1 and 4 ducats.

There were some coins on the list that didn't count. This was largely due to the Office of Domestic Gold and Silver Operations (ODGSO), which was established to oversee the aftermath of the 1933-1934 gold recall. They kept track of which coins fell under the "rare and unusual" exception and which did not.

ODGSO eventually drew a clear line between pre-1959 coinage, which was legal to own because it was "rare and unusual," and 1960 issues, which were "not so rare and unusual."
There are a variety of bullion coins available today:1) the "pure" bullion that is produced by a number of sovereign governments and is uncirculated and weighs 1/20, 1/10, 1/4, 1/2, or more ounces; 2) a proof version that is also produced by sovereign governments and is primarily intended for collectors, and 3) the gold coin that was originally intended for circulation and has primary value in bullion but has a slight numismatic premium (generally not more than 15% above the spot price on any given day). This comprises:
