<p>[QUOTE="Mac McDonald, post: 7816035, member: 117420"]On this topic/thread and getting back to the Lincoln Boyhood Cents as related, I have two sets of the four different 2009 copper pennies (8 total)...each in its own 2x2 stapled, white cardboard holder for 11-12 years...in addition to two sets of 4 in the OGP plastic case/holders...ALL stored in the same cool/dry place with no other known influence of contaminants, etc. Not one of the eight cents in the 2x2 individual cardboard holders is toned even a little...no indication of anything to the naked eye...not spots, not darkening/fading...totally MS/BU as if just off the press. The other eight cents in the OGP holders (two, with four coins each) are toned between moderate and total...not unattractively but certainly obviously...darkening and no longer BU. You'll never convince me this is in any way random or environmental, etc...more to almost an assurance of something...a reaction of one or more components...in/of the OGP/holder. Except that some of the same OGP holders contain pristine cents...totally unaffected. Go figure. Understand it CAN be different and effected by other things mentioned...but not in this instance. It's in/from the OGP holder...or on the coins before holdering...something. For what it's worth.[/QUOTE]</p><p><br /></p>
