Makes sense... I could see a quick dip changing the color without killing the luster...

A lot of the SMS cents are lighter colored than others. I have no clue what causes it but it very well could be something in the washing process at the mint.
Time don't fly, it bounds and leaps.

Interesting. Thank you for posting the pair for comparison, instead of just the one in question.

I figure it has to have been messed with... it just looks so different, but the luster is still there...
I'm also not sure if these are really sms coins, need to research sms markers...

Higher zinc content or exposure to some heat. Take them out of 2x2's and take better pictures of BOTH sides.

  These pretty accurately show the true color of the coins. Both are identified as "SMS" on the 2x2's. |

The color differences are amazing. It almost looks like an off-metal strike.

Looks like heat exposure to me.
Experiment - Take a copper cent and heat it with a torch, see what happens.

Ok. Took a torch to a 70's cent:  Doesn't look as nice, but has a similar light color... maybe with a little more finesse you could end up with something like the '65. Why you would want to do that I don't know... Edited by SomethingIsFishy

Well, your SMS cent may not have been torched but it could have been hot enough over a long period of time to cause the zinc to migrate to the surface since it has a lower melting point than copper. Here's one I carefully heated:  |

That looks very much like mine... I think we have the answer! Of course, now I wonder how it got that warm... if only coins could talk...
