Tips for taking great photos:
1. Take your photo with a digital camera and take several, so that you can choose the best one on the computer;
2. Take your photo in daylight and without flash;
3. Use the macro function of your camera;
4. Try to photograph the coin as much as possible filling the screen and upright;
5. Use software on your computer to fill in the middle of the coin;
6. Many software can rotate the photo slightly so that the coin is upright.

0. ensure a smooth background. Most coins look very nice against a dark (black) background, but if you don't know how the color correction settings of your camera and / or photo editing program work, light blue is often better. Cameras are set by default to properly photograph pictures with a good amount of sky on them.

2a. use a (table) tripod
2b. use the timer function

Then you never have to use the flash and your photo will still be sharp.

4a Full-frame (depending on the setting of your camera) is less important. Keep in mind that the maximum useful size of the 'uploadable' photo is 1000x1000 pixels. In other words, 1 Megapixel. You would therefore have to resize a full-screen photo of 8 mexapixel almost by a factor of 3 (no, this is not a calculation error), whereby a lot of detail can be lost if you do not know exactly what you are doing with your photo editing program
If you set the camera to 4 megapixels, it is sufficient if the coin fills about half the height of the image. Then you can simply crop the photo on the computer and you hardly have to enlarge or reduce it. And if you used a light blue background, you have the added advantage that, because you photographed more background, you often get better automatic color correction.

I always scan them, as far as I am concerned it goes faster. At 720 DPI you get a clear picture of the details on the coin.

Another tip: good photos of many coins can also be found via Google. Just make sure you have permission to use them, but that's usually not a problem if you explain what it is for.
