  Wrong! Slabs are not air tight. Toning will occur. If they are stored properly (not too humid especially), toning will be slowed significantly. That's my understanding anyway.

  Yep, slabbed coins still need to be carefully stored. Keep a variety of 'no-nos' away: rubber bands, wood, dyed velvet. Keep unnecessary paper products away. Use silica gel to keep the local humidity down. If you have red coppers in slabs, put the slabs in Intercept Shield boxes and/or put some new 'sacrificial' cents nearby.
  
  And...after doing all this, some coins may still tone while in the slab ('turn' is more like it), because they were dipped and improperly rinsed just before they were sent off for grading and encapsulation.

  Coins can be tarnished in the slab - both artificially and naturally - as most people here already know. Cheers, RickO

  I will take the previous comments a step further....if the coin has some type of reactive residue still on the surface when it is slabbed then even keeping it in a neutral environment may not ensure that the coin remains untoned. Plenty of dipped coins that aren't properly rinsed turn in the holders even in the best of environments.
  
  
  but the basic answer was as stated.....coins can and do tone in slabs but not all coins all of the time.
