Hey all. I just discovered this silver bar in my collection and I was curious to find out more about it. I've searched and searched, but with no luck. I have a Johnson Matthey & Mallory 1 Kilo Silver Bar. It has a CANADA stamp and a Maple Leaf logo engraved. Here is a picture I found of one on the internet, but that's about all I could find. Oh, and what's the best cloth and cleaner so I can restore it to its natural beauty?
