I have noticed this phenomenon for years, not just with conductors but with
a lot of commercially available equipment.  The sensation is as if the
surface of the item in question is "sticky-buzzy"(tm) and a finger moved
over the surface of such an item seems to vibrate at the 60 hz (In North
America) line frequeny.

One such device is the SONY ICF-2010 shortwave radio, when operated with
the 4.5v AC Supply, when touching some of the metal parts on the radio
during AC operation.  It is not just a defective set, as I have owned THREE
of them, and each had this phenomena.  

For the record, I am one of those persons who perspire a conductive
material (oil based) from the fingers.. i.e. I leave good fingerprints.

Other equipment I have owned also produces the effect.
