One of the very first coins produced by the United States will go on the auction block today in Columbus, Ohio.
The 1792 half dime is in exceptional condition and will likely sell for 500-thousand dollars to two (m) million dollars. That's according to Mark Borckardt, a senior cataloger for Dallas-based Heritage Auction Galleries, which is selling the coin.
Borckardt says one could argue that this coin is the most important one ever produced by the government. Smithsonian Institution rare-coin curator Richard Doty says the coin is thought to have been struck on silver provided by George Washington.
Two badly worn half dimes also will be auctioned today.
