ATS Thread "Coin left behind on Mars?" by SuperSlovak

Excerpt

The above fifth and sixth images demonstrate a small round flat disk on
the ground pointed out with the yellow arrow apparently caught in a rock
crevasse that is also filled with what looks like soil. If it is soil
and not dithering smudge image tampering, the soil covers roughly half
the disk hiding that portion from view. Note that the surface
of the disk reflects sunlight a little more than the adjacent rock surfaces
and more uniformly.
This suggests that this object may very well be smoothed metal.
Also note the uniform thickness of the disk as demonstrated by
its left exposed portion casting a short shadow against the rock surface
it is laying on.
Now this disk obviously looks like a metal coin and is very suggestive of that as
many of us will see it. However, without the fine detail of the disk's surface,
we can't be conclusive beyond this being just very suggestive.
This inconclusive situation to a large extent is a function of the very high .
jpeg compression on this imaging as released for public consumption.
This object is plenty close enough to the Spirit rover panoramic camera
that such details should be available to us if this imaging is as good as
it was suppose to be.
