I have had this silver bar for nearly 30 years now but it may be much older.

I am looking for information on it.

1) Any idea how old it is based ion the serial numbers?

2) Anyone ever seen a 7 OZ bar before? I see lots of this "Old School" style 10 OZ bars on Ebay but never seen a 7 oz for sale. Is this a Rare weight?

3) Any ides of the value? I see similar 10 OZ bars on bringing an incredible $35-$40 an OZ but never seen a 7 OZ before

Been using this as a card capper for many years now.

Thanks,
Doug
