I have inherited a large collection of Gold, Silver and Copper coins which I am going to try an photograph. The intent is to get the best resolution possible for a catalog to distribute in a PDF.
I am not having much luck with the lighting and detail. The macro seems to be doing it's job, I'm just not getting the lighting.
Should I use a light table as some online sources suggest? Use background? Is there a better way?
Non specular , semi-diffuse lighting works best. Do not just shoot straight on, but vary the camera angle and lighting angles up to about 20 degrees. Each side of the coin may require 2 or 3 different angles so as to approach an accurate portrayal for valuation purposes.
You can send them to me, I'm sure I can do it. LOL.. As mentioned by Imagemeister, but I would try addition White lighting, quartz would be best. Then you can use a telephoto, with you micro lens in that to get you back a bit.
When you shoot at a slight angle to the face of the coin it will help if you stop down the aperture to F16 and manually focus at taking aperture ( or therabouts )so you can be at a hyperfocal distance to maximize DOF.
I have a large collection of old dimes and I always wanted to find a way to protect them and I never thought of taking pictures of them. Thanks for a great idea.

I gave a answer to this a while ago, you need to make a Black box lighting unit. very easy to make.I sent in photos and instructions to this site. maybe about 2 months ago.

If you have a flat bed scanner, try just laying them on the glass surface and scanning them just like a page of paper. I used to do this with watches and everyone was amazed at the quality.

I had a similar requirement. I used a light box, a tripod, and a good macro lens. A lot of patience and time helps.

Thanks for posting, Soloman, but can you also post a link? I searched on site for 'Black box lighting unit', but got a list of unrelated lighting units. Thanks.

The "Flat Bed Scanner" is the perfect tool for digitizing a coin collection, coins are like paper, they are flat. Something you might want to consider is the background of the scanner bed (the cover). If you leave it white the copied background may turn out grey and need Post Processing (PP) to correct for the catalog publication.
If you secure a dark colored paper on the inside of the scanner lid you can control the overall appearance of the scanned coins, and in the end the only PP required will be cropping each coin for the catalog.
If you decide ahead of time the nature of the catalog (color, or B&W) you can reduce your PP even more by selecting the background shade.
If you do not have a flat bed scanner you can perform wonders with a good Macro lens and two lamps placed at 45 degree angles to the coin.

Assuming you have a flash, bounce it off a white surface (reflector or ceiling).
