  I would think the toning would change if it were placed into an different album.
  
  Different chemicals and such in the New album.
  
  I do not think the toning would progress much if removed from the original album and stored in an inert environment.
  
  Unless it had surface contamination.

  If the coin is super beautiful, stop the toning right away, and get it in a protective case.

  Are we talking about silver? I agree with EOC. If the coin is nice now, you risk the toning progressing to what most would call corrosion (even though scientifically there is no difference). Just taking it out of the album and moving it to a protected environment is probably enough, but if you're worried about it, an acetone bath would remove any leftover contamination without disturbing the color. Be advised that this will also remove any dirt, debris, or gunk (character) that is on the coin.

  Toning is the effect of light bouncing off a surface. When metals oxidize a layer of corrosion forms on the surface. Then when light bounces off the surface it does so at different angles which creates different frequencies of light, which our eyes perceive as color.
  
  
  
  
  
  So unless the layer of corrosion is removed from the coin, the toning won’t change.
  
  
  
  If you move the coin into a different album, new corrosion could form the different chemical composition of the new album which could change the layer of corrosion. This would cause light to reflect at different frequencies and you would see different colors.

  So, I have taken a coin, I received 2nd hand (a SAE) that was toned/toning a certain way.
  
  
  
  I left it that way for a little while then moved it to a different holder (one of the small, cardboard, holders) and I did notice that it continued to tone but in a different way.
  
  
  
  So, I would extrapolate that this would be true in most/all instance. Just no guarantees whether it would be the way one wants it to tone

  I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment

  Thanks for the replies to this question. Just to clear things up, I do not have an album at this precise moment with said coin. This question was just that...a question of a hypothetical coin that is toning.
  
  
  
  I really appreciate the insight to the answers here.

  
  Later, Paul.

  Anyone here ever attempted this?
  
  Just wondering...

  
  
  NOOOOOOOOOOOOOOO, don't do it!!!!!!!!!!!!!!!!!!!
  
  I did that once and it turned ugly as all hell. Don't do it.
  
  

  The bitterness of "Poor Quality" is remembered long after the sweetness of low price is forgotten.

  He's asking about overexposing a coin. If it tones one way in album A and another way in album B, what happens if you take it partially toned from A after it starts toning and put it into album B. You will probably get something that is not as nice had it fully toned in album A or B. The terminal result of too much/overexposure is a coin that will be almost black.
