Thinking back about all the pro's and con's about us landing on the Moon, then looking at the possibility of this topic. By that I mean the pessimistic view point is what if there was no Cent sent to Mars anyway? Who could prove it? How does anyone really know if it is a Lincoln Cent and what is the date on it if it is there at all? Who is going there to see if it is there? With all the STUFF the government tells us that we never really know if true, this entire coin thing could be a story invented by the Mint to inspire more ooin collecting.
A cent being Copper could start to combine with very little Oxygen to form Cu2O on the surface. With a small amount of CO2 and a bit of moisture, that could start a reaction creating [CuCO3-Cu(OH)2] or Copper Carbonate. This would eventually rot away that entire coin, if it is really there.

Oh, that's excellent.... a Mars Lincoln Cent conspiracy. There could be a whole cottage industry built around it - investigations, books, youtube video and movies for the next 100 years.

When you think about it, a 1909 VDB is kind of being cheap compared to the whole Curiosity budget. They could have sent a 1909 S VDB. Knowing it would be harshly clean-up, a 1909-S VDB could have been purchased fairly inexpensively that was previously cleaned or had impaired surfaces. Ken Edgett paid for the coin with his own funds and could have sprung for this type of up-grade I would think.

And, what about the Moon. Do think one of the Moon astronauts might have left a Buffalo nickel (or something similar) on the Moon surface?

The surface of Mt. Sharp and Gale crater have some of the highest concentrations of sulphur--up to 3.2%, so dust could possibly interact with moisture, form H2SO4 and react with the copper.

Here ya go--the first picture of the MAHLI calibration target on Mars, including the 1909 LWC.
I have included a full-resolution image, as well as a portion of NASA's caption, the entirety is here.

The MAHLI calibration target includes a penny at the center of this image, plus color chips, a metric standardized bar graphic, and (just below the penny) a stair-step pattern for depth calibration.

The coin is from 1909. That was the first year Lincoln pennies were minted and the centennial of Abraham Lincoln's birth. The penny is a nod to field geologists' informal practice of placing a coin as a size reference in close-up photographs of rocks, and it gives the public a familiar object for perceiving size on Mars easily.
