Blue is one of the colder color temperatures. You'll usually see that when using LED or even fluorescent lighting. It's kind of odd if you're getting blue using natural light. If you are it most definitely is the white balance as others have mentioned above. Some camera's have presets where you pick the one what works best or you can put the camera in Auto WB. I'm assuming you're stuck in a bad WB preset in a bad manually adjusted WB value for the light you're using.
If you can manually adjust your WB though, that can be helpful. For example if you were indoors using incandescent light bulbs at night your shots may be coming out yellow or orange. Where ever your camera is set to right now which is causing the blue with natural light might very well cancel out the orange from incandescent light resulting in a 'normal' colored shot. If you're getting blue with your light, try to use a 'warmer' WB like the Sun or Lightbulb setting (higher color temperature) to cancel out the blue.

I wouldn't recommend using the presets, use the custom preset white balance feature.
You setup your camera, coin, and ligthing to the exact setting that you're going to shoot. Since you're using flourescent bulbs, let the bulbs warm up for a minimum of 10 minutes. Place an 18% gray card or a piece of white printer paper where the coin will be imaged and then set your custom preset white balance based on that exact shooting environment. If you change your lighting/setup, then repeat the aforementioned steps.

Hey Louie: What size light bulb would you suggest? I have a 40 watt Daylight one now, but I can always take it back. Thanks.

The more wattage the better. I currently use daylight balanced flourescent bulbs with the output equivalent to 75w, but I saw Lowes had some with 100w, so I'm going to pick up a few of those. Because the brighter you can get it, the more you can stop down your aperature and increase your shutter speed to create sharper images with a better depth of field. I'm a novice photog, so don't take my word as gospel...this is just what I've been learning through advice from pros and LOTS of trial and error.

Ok. So things are much better. Got the batteries, switched light bulbs, adjusted the WB and started shooting. Big improvement. Most everything I own is toned so getting the correct color has been tough. Alot better now. Seems easier to capture the correct color of the toning on silver coins. Copper is a different story. I will still need to work on the copper. It's not right yet. But I'll keep doing the trial and error thing.
Thanks you guys for helping me out with this. Really appreciate it.

If you use an 18% gray card to shoot at and adjust your WB before you shoot ANYTHING else, that will give you a one stop shop White Balance adjustment...

Newbismatic, thanks for your reply. Ummmm..... What is a 18% gray card? I can go to Corvallis tomorrow to the camera shop to get one if they have it, but I don't know what it is. I've been there a few times already. Problem is the one girl that works there part time is an Oregon State University senior and I have trouble concentrating on camera issues when I'm around her. There is a guy that works there also, maybe I'll get him to help me. So, I'll post what I found out about this gray card thing. Thanks again.

I have problems capturing toning with my camera also. It does untoned coins good enough for the web but when you are talking about allot of different colors I guess my 3.2MP $25.00 camera is just to outdated to capture them well. Its like the camera gets a little confused, but I have seen quite a few others say their more expensive camera doesn't capture toned coins well also. I think its more of a lighting and angle thing than a camera thing

I don't know if this will help but I find that if there are blue objects close by my image is blue. Same if there is red close by and so on with other colors. I just move the camera to a different angle until that color no longer appears.

 This "was" the problem I had been having. Got the gray card yesterday for $3.95, but my Mini Schnauzer puppy chewed it up. Going to get another card today and will post pics. Have some pics I did yesterday that are a great improvement from this one. All thanks to you guys and the great advice you have given me. Very frustrating this has been, but again, you guys got me through it. Thanks so much!

 This reverse proof is a "Cull" (Ding on the sun) but I was experimenting with shadows and it came out pretty good.

the color definitely looks better. Are you happier with the photos now as far as white balance?

Well, I like it much better than it was, but that doesn't necessarily mean it is correct yet. You guys probably have a better eye for that. What do you think Bryan? Do I need to take further steps? Always open to suggestions. Thanks.

in my opinion the color looks pretty good, now you just need to adjust lighting to get the picture exactly the way you want it. But I think the WB is pretty dernh close if not right where you need it to be
