Silver 1743 Milled Pillar Coin?

1743 is not a rare date and if George Washington did throw a silver dollar across the Potomac river it was an 8 real coin that the colonials called dollars. There is a lot of history to the coin and you only scratched the surface. It was the major silver coin in Asia from it's beginning to its end. Most pillar dollars today sell for $100-$300 depending on grade. The lower the grade the less money, the higher the grade the more value. A lot of U.S. coin dealers know little about them so if you sell check out more than one dealer see several and make sure they know what they are doing. You will get short changed if you don't.
