Anybody have any idea what this is?

So,,, what the heck is it. It was in a 2X2 labeled "1844 one penny model E190 Pattern" this one was with a brass center and there is another one labeled the same but with a silver center. I know they are not major items, but--- I have no clue what they are--Anybody know?

Some coins are just plain "Interesting"

Here is a pic of the silver piece. This one has a different alignment than the brass piece. This one has a medal alignment (upright when flipped) while the brass piece has a coin alignment (reverse inverted when flipped) This piece is very dirty and not as corroded as my pics make it look. It also has a major die break on the reverse. Thanks again guys.
