Pedro,
These all look like Mardi Gras tokens that are thrown to the crowds as souveniers at the Mardi Gras parades every year before Lent in New Orleans, Louisiana. Over the years there have been hundreds, if not thousands of different tokens. They are not worth too much, though some people do collect them. Many of these tokens were made by Osborne Coinage Co. right here in Cincinnati, Ohio.
