Help! What am I doing wrong?

Well I was just sent a batch of coins to photo, mostly nice white coins. Anyhow I find I am struggling with the lighting. Not sure why I seem to struggle so much with lighting, but I do. I seem to be getting "dark images" even though I have 4 OTT lights. Any Help?? Sample Image...

Here is another example...

A few more attempts...
I think this is best of the bunch....

This one looks overexposed....

This one looks out of focus and unvenly lit to me....

Thoughts?

Late date franklin tend to be very shiny. That will cause you to overexpose the highlights and underexpose things like the field. Need very diffuse light.
The only thing I can offer is try different lighting....???
only problem that i see is they is too BIG!!
You could also try moving the lights around a bit.
The photos look great unless in hand the coins are truly gleeming white

Color is pretty spot on.
but I was thinking the contrast is set too high
so I lowered the contrast and increased the brightness
your pic is on the right
One thing you will have to keep in mind, if you do not take the photo at a slight angle you will get a reflection of your camera. (Bottom two photos)
Let us know how you turn out,

<< <i>What camera are you using? >>
Canon 30D is being used for these photos.
As for the contrast, I have not done any post image editing in that regaurd.
<< <i>Are these all NGC graded coins.....we all know how difficult it is to get light on the surface of NGC holdered coins? >>
These 2 are PCGS holdered coins. One is a rattler.
