2006 DDR ?

It is a DDR. Which one will be the next challenge. In order to do an overlay of the them to see which one you have, you would need an image of the cornice (above the columns) and include a few steps. That way image image could be cropped to see which one it could be. Markers would also help, not not always found to match a certain die. But always nice to check for.

I checked the site and there are a couple that are close, but yours is not either of them. In order to match a certain die the location of the bar, the length and width must match in order for it to be from a certain die.

On a different question: The shiny look that you don't want you might try to diffuse the light that reaches the coin. If the bulb you are using is to how, then a diffuser shouldn't touch the bulb. You might try making a curtain between the bulb and the coin with something like A plastic grocery bag or white tissue paper or something thin to cut down the glare that come through on the coin. Again if the light source is hot don't put it near the bulb, but between the coin and the light source. That way it cut the very strong light creating the glare you don't want. See if this helps. If you don't get it on the first try, keep trying. Sometimes you have to make the light source work for you by experimenting with different ideas.

I think it's worth hanging on to for now.

This one would be worth including in a package with other coins, but would not quite be worth sending by itself. Doubled dies like this are so numerous, it doesn't surprise me at all that there are coins being found regularly that are not yet listed.

Doesn't matter which side it's on, but the proof coins would be more valuable. They are far more scarce than the MS examples.
