Check out this new video camera from Kodak. it is water proof to 10 feet, shockproof, dust proof and has a Macro setting for the close-up shots of your coins.

Just ordered one from Walmart for $159.00
I had the first generation of this camera and it was very nice but did not have Macro setting and was not shock proof. I sold it because of no Macro and said I would get another if they ever added the feature. It is about the size of a smart phone and was very easy to use.
