Another day of Metal Detecting

Did some more metal detecting at the Zoo Field today.  I found a Zoo souvenir penny, and the two pennies below it are Wheat Pennies, a 1944 and 1953.  A total of 82 cents.  I know that doesn't sound like much, but it's the most money I've made in weeks!
I'm not sure about the medallion. It had a little oval piece on it and I think it used to hold a stone of some kind.
The large hunk of metal on the left, I have no idea what it is.  Maybe part of a gate, fireplace grate, or something similar.  It's heavy.
