|XXXX Nickel Babbitt.|
This was described as pure nickel by a seller who (a) had obviously never seen pure nickel and (b) didn't know that "Babbitt" refers to a bearing alloy consisting typically of tin, lead, antimony, and copper. "XXXX Nickel" is a trade name for such an alloy that also contains a small percentage of nickel. I have it listed here under nickel because while that isn't the most abundant element in the sample, it is the most interesting element, and it is after all stamped right there on the bar.
