More likely it's just corrosion or tarnish on the connector surface caused by 
oxidation. I never insert a phone or miniphone plug into a jack without giving 
it several rotations back & forth, to scrape off any accumulated tarnish. 
Also, if you leave the plug in the jack for extended periods of time, i.e. 
months, and if the plug & jack are of dissimilar metals atmospheric pollution 
will cause a mild form of electroplating at the contact points. This will cause 
intermittent connections.
