<p>[QUOTE="Conder101, post: 395295, member: 66"]Yes all of them. The presses need lubrication, the dies have a coating of oil to prevent rust and the planchets themselves are oiled so they will move through the feeding tubes and equipment easily. So yes all of the coins come from the mint with a light film of machine oil on them. (Remember the proof gold buffalos back in 2006 that had red stuff on them and it was determined it was oil and traced back to excessive oiling of the planchets. Even the proofs are oiled.)[/QUOTE]</p><p><br /></p>
