Another new Lincoln penny unveiled, and it's still useless

An arguement over a penny doesn't seem worthy of calling police in, but for Lincoln penny collectors, things got a little heated Thursday.

Lincoln's birthday was Feb. 12, but the bicentennial of his birth is being celebrated all year. The yearlong celebration by the U.S. Mint continued with the release of the third of four new pennies, causing a shouting match among collectors outside the Old State Capitol in Illinois, which is depicted on the back of the coin.

While the crowd lining up for the new pennies was mostly subdued, Springfield police intervened when two groups of visitors argued over who was cursing or cutting in line, according to the State Journal-Register in Springfield, Il.

The back of the penny released Thursday shows Lincoln delivering a speech outside Illinois' Old State Capitol, where he served as a legislator, delivered a speech on slavery and ran his transition office after being elected president.
