Is it encapsulated or exposed. If exposed, that was just plain dumb IMO.

Ken Edgett with Malin Space Science Systems, who bought the coin to be included in the calibration target, tells why:
"The penny is on the MAHLI calibration target as a tip of the hat to geologists' informal practice of placing a coin or other object of known scale in their photographs. A more formal practice is to use an object with [its] scale marked in millimeters, centimeters or meters," Edgett said. "Of course, this penny can't be moved around and placed in MAHLI images; it stays affixed to the rover."
He goes on to describe a purpose for its exposure to the Mars environment.
"The public can watch for changes in the penny over the long term on Mars." "Will it change color? Will it corrode? Will it get pitted by windblown sand?" Edgett said.

Well...based on the "before and after" pic posted earlier...it does indeed appear that good ole' Abe has some PMD from the sand blasted surface the cent now has! No it was not a matte proof! Lol

I wonder what a CO2 atmosphere does as far as toning goes.

I wonder, if they ever get that thing back, how much it would sell for? I can just see the slab

Or will we need a new grading system if they un-earth (un-mars?) some alien currency of some kind?

Even closer look. Credit: NASA/JPL-Caltech/MSSS This close-up image shows Martian sand grains that settled on the penny that serves as a calibration target on NASA's Curiosity rover. Image released September 12, 2012.

TreeMonkey--thanks for posting that! I'm now reminded the coin is roughly parallel to the ground. It should be interesting to see how much dust collects.

If there are any Martians hiding out there somewhere, and if like us at all, one of them surely is a bum, out of work, needs cash. Wanders by that rover, grabs that coin, comes to Earth and tries to buy something with it. Surprize. It's worthless for purchasing. Gets mad, returns to Mars, smashes that rover to pieces and sells the scrap metal to a recycler.

Updated photo of the 1909 VDB Lincoln Cent on Mars. This was shot on 10/2/13. It's at the maximum detail level for the MAHLI, Mars Hand Lens Imager at 14 micrometers per pixel. I want one for Christmas!  Full details at http://photojournal.jpl.nasa.gov/catalog/PIA17365 and a 5.7 MB .tiff file that shows the highest detail that the camera can pick up. I'm not going to update all the other Mars/Cent threads, just this one.  Ben

Wow--thanks for posting that Yokozuna! You can really see the progression of dust settling on the cent. I cannot tell if that is dust of different colors, or some reaction of the copper?  Given the radiation and (some) water on Mars, it might be...?

I wonder how much it would sell for at an auction.
