Old Lead Belt Buckle? And Other Unidentified & Interesting Finds

[Vldetecting]

I found this belt buckle looking item made of lead a week ago. It is very heavy and has the size and shape as an american civil war belt buckle. It does appear to have a interesting pattern on it's obverse but it's hard to make out what it is. I could really need some help to identify this item cause it's very interesting (measurement in the photo is in centimeters):



I also found some other unidentified items. The white thing in the photo is made of porcelain and looks to be handmaid and has the size of an us quarter (it almost looks like a checkers game piece):



If you have any thought about these items please let me know and happy hunting
