What are those?

Copper pennies that were pressed in a coin souvenir maker.

@Nitro Does that mean they started out as actual pennies?
Elongated coin - Wikipedia

Yes,and probably illegal as the day is long to boot

@Nitro According to the Wikipedia article in the link:
"The process of creating elongated coins is legal in the United States, almost all parts of Japan[citation needed], South Africa and parts of Europe. In the United States, U.S. Code Title 18, Chapter 17, Section 331 prohibits "the mutilation, diminution and falsification of United States coinage." The foregoing statute, however, does not prohibit the mutilation of coins, if the mutilated coins are not used fraudulently, i.e., with the intention of creating counterfeit coinage or profiting from the base metal (the pre-1982 copper U.S. cent which, as of 2010, is worth more than one cent in the United States).[8][9] Because elongated coins are made mainly as souvenirs, mutilation for this purpose is legal."
