Has anyone had a coin's toning or color change soon after cracking it out of a slab?

Copper inparticular?

Yes. Almost every coin has something on it's surface.
Some from before it's slabbed and some after being slabbed.

Once you take it out it gets a blast of oxygen and whatever humidity at the time.
That's all you need for a reaction.

But slabs aren't airtite, right? And a slab which has been crossed, upgraded, etc has been opened at one time...

What I'm getting at, is it safe to crack my coins, put them in Whitman Holders, and store them all in the same manner. It would make my sets sooo much nicer, and show how much effort I've put in to making my sets prefectly matched. Has anyone else done this? Had good experience's? Bad?

Thanks!

If you have no problem with loosing value over time, go right ahead.
They will look great all lined up in an album.

Down the road if and when you decide to sell, you will be out the grading fees.
I would bet they won't grade as high.

I have been thru this over the years and now wish I had left them in the slabs from the start.
Circ. coins are just great in an album. MS copper is not a good idea.

Yeah, an album would not be a good idea, but what about plastic holders? I know the holders would be okay too, but just don't want the act of moving the coin from the slab to the holder to start a chemical reaction as you mentioned. The coin was certainly protected in something other than a slab up until some date since 1986!

Edited to say... how many rb Lincolns have I seen though in rd pcgs holders? Way too many
