David Hall: The 1937 Roanoke is one of the least rare, yet most popular silver commemoratives. There were 50,000 originally struck and they were to be sold at an issue price of $1.65. However, by 1937 the first wave of commemorative collecting fever had subsided and 21,000 Roanokes were returned to the Mint as unsold and were subsequently melted.
Today, the Roanoke is quite popular, probably due to the fact that it was a very "legitimate", historically important issue (commemorating the first settlers in Virginia and the birth of Virginia Dare) and the Roanoke is a beautiful design. In terms of rarity, the Roanoke is one of the more common silver commems in uncirculated grades, especially in Gem condition. It is in the same rarity class as the Elgin, Norfolk, Wisconsin, and York. It is more common than the Albany, Antietam, Gettysburg, and New Rochelle.
The typical Roankoe has highly lustrous, mark-free surfaces. The average grade is MS64 to MS66 and MS67's are fairly available. Roanokes come really nice!
