What's going on here?

How is two brand new cents...one slabbed and one not a good example of how the type of luster a coin has determining the toning?

the one that slabbed will have original luster, from being slabbed, and the other one will start to tone from being exposed to the air, which over time there will be no more original luster left

 

Just because a coin is slabbed does not mean it is 100% protected from toning and other environmental factors.

 

You've never seen a coin tone in a slab I take it? While the raw coin is more likely to tone faster...they are still the same coin and will exhibit the same toning process as they tone. The coin in the slab may tone slower...or if placed in a very controlled environment may take decades or even centuries to tone, but it will.

The luster is still present either way. The toning may subdue it, but it's still there because the metal surface of the coin that creates the luster is still intact.

 

correct

 

So then...comparing a slabbed coin and a raw coin wouldn't really be a good way to test your theory.

 

its the perfect way, a brand new cent thats been slabbed will always stay red, everything else does this:

A copper coin when first struck exhibits a lustrous reddish orange color. These specimens are prized by coin collectors and carry a value premium over identical coins that are starting to turn brown. Most coin collectors will agree that if a copper coin has retained about 90% of its original orange red color it will be designated as "Red" and abbreviated in its grade as "RD".

Once oxidation and chemical reactions start to occur on the surface of the copper coin, its color will start to change from reddish orange to brown. This may include some areas of the coin that are approaching a chocolate brown color while other areas still have some of the original reddish orange color. A common measurement is that between 10% and 90% of the original orange red color remains. This is termed as a "red brown" coin and is abbreviated as "RB" on coin grading descriptions.
Copper Coin Color: Brown (BN)

Finally, when almost the entire surface of the coin has reacted with the atmosphere such that the surface of the coin is almost entirely a chocolate brown color, this is considered a "brown" coin and is designated as "BN" on grading descriptions.
Shades of Copper

 

So, do you think a slabbed coin can't turn? Because...you're responses initially suggested that you understood they could and then you contradicted yourself. Trust me, coins can tone in the slab and they do. It might happen slower...especially if properly stored. But, a properly stored raw coin shouldn't tone either. Bottom line, slabbed coins can and do tone.

Also, your posted descriptions of color change say nothing about luster changing because those two things are different.

 

heres the bottom line, coin in thread is brown, which has no orginal luster left

 

If one of my ms-67 presidential dollars goes brown, because of slab leaking, then that a bad slabbing company

 

I disagree...I think those red areas around the devices is original luster.

 

Slabs don't completely protect the coin from the environment. They are not air tight. The slabs still must be properly stored. If the owner fails to properly store the coins, it's not the TPGs fault.

 

But again, where do you have verifiable proof that brown coins don't have mint luster? Just about any pic of a coin listed as MS BN would prove that wrong. The color of a coin and the mint luster it has do not necessarily go hand-in-hand. Would you say that this coin has no mint luster? Slabbed as MS65 BN. http://www.ebay.com/itm/1886-T-1-In...55?pt=Coins_US_Individual&hash=item2c7b00462b

 

its a good though, but would never past in a sale listing, as some orginal luster still being there, at least not for me

 

this is what pcgs say about brown copper coins:
Brown
The term applied to a copper coin that no longer has the red color of copper. There are many "shades" of brown color – mahogany, chocolate, etc. (abbreviated as BN when used as part of a grade).

 

Ok, and that has no mention of mint luster.

 

Exactly, it says the color changes...but says nothing about luster. Brown MS coins still have luster, it's subdued but it's there.

 

how are you going to see the orginal luster, under the brown color, or oxidation, which changed the orginal color

 

thats why some people clean coins, to try and get the original luster back, and that ain't ever happening

 

The luster isn't really "under" anything as far as I understand it. Read post 8 of this thread. Mint luster has to do with the surface topography of the coin, whereas color has to do with chemical reactions. Circulated coins lack luster because the topography has been flattened...a coin that has been not circulated, cleaned, or otherwise tampered with should still show mint luster to some extent no matter what color it is. XF coins are circulated, but not the extent that they lose all of their mint luster.
