Don't worry too much about the lead, elemental (ie metallic) lead isn't really much of a hazard. It becomes more dangerous when it is in compounds such as oxides (used to be used in paints) because that increases the bioavailabilty.
There will be a thin oxide layer on the outside, but as long as you don't ingest it, you will be fine.
In other words: touch it all you want, but thoroughly wash your hands afterwards.
