I am a brazilian and had the chance to deal with Nevada Coin. I was there to sell some gold coins and they paid me the best price I could fetch in Las Vegas. They are professional, courteous and trustworthy. Before visiting their premises I got a tentative appraisal by phone which I found reasonable. In the shop the attendant offered to approach the manager to get me a (gasp) BETTER price. Do yourself a favor and don’t bother talking to their rude and unprofessional competitors. They will treat you like a moron and quote prices accordingly. For Nevada Coin, five Stars all the way.
The 1921 Peace Silver Dollar is one of the nicest examples of silver dollars the United States has minted and came about thanks to the Pittman Act of 1918, which melted millions or Morgan silver dollars in support of the British and American war effort during WWI. The coin was designed by Anthony de Francisci and the portrait of the liberty face on the 1921 Peace silver dollar was modeled after his wife.
The high relief style of the 1921 Peace Silver dollar allows it to stand out as one of the more unique designs for United States silver dollars. Even in the worst condition, the 1921 Peace silver dollar can carry a premium above the rest of the common silver dollars in the Peace series and, in much higher conditions on the coin grading scale of 1-70, the 1921 Peace silver dollar can be worth several hundred dollars.
