I own a few nice coins like maple leafs, eagles etc. but when I bought my bulk of physical silver under $7 I always went bang for the buck. Any 1oz coin stamped .999 will do. You are paying for the element Silver and nothing else. These days I am loving the 100oz Academy bars. They are made from recycled Silver so they are GREEN plus it is absolutely the best looking bar on the market. If you loved legos you will love these bars.
