The Morgan Silver Dollar top of the pops

The Morgan silver dollar is today one of the most popular of all collector coins. First minted in 1878 following the passage of the Bland-Alison Act, the new dollar was named after its designer, George T. Morgan. Political pressure by powerful silver mining companies, in a gambit to stabilize the price of their commodity at artificially high levels, created the impetus driving the legislative action. Bland-Alison led to the overproduction of silver dollars, resulting in millions of these unused “cartwheels” languishing in bank and Treasury vaults. Indeed, few coins have ever been released under more dubious circumstances than Morgan silver dollars. Minting continued until 1904, and then again for one more year in 1921, when the series finally came to a close. More on coins here
