Valley State Bank silver bar

[Harp]

Need a little help here. I have recently bought a 100 ounce bar of silver that says. "Valley State Bank" it also has a logo formed out of the letters VS on the front and covering the back. On the front it also says ".999 Fine Silver 100 Troy Ounces Pure", it has no serial no. I have done many internet searches and found nothing at all. Any help would be greatly appreciated.
