Got Photoshop? You could make an independent shadow (drop the backgound on the coin image, make it black and blur it, save as .png).
Then you could put the same actions on the shadow as the coin.
You can fake it within Keynote although you won't get a soft edge to the shadow.
In this image I took the background out with instant Alpha, then with image adjust made it black and then made a dark one and a lighter one with opacity. Now, put the same actions on all three, you might be able to group the two shadow pieces and put the action on just the two pieces, you will have to experiment.

Thanks,This "eclipse" approach would work if ancient coins were truly round. Unfortunately, their outlines are highly irregular. As an example, try this:The black background works wonderfully with instant alpha. I guess what I'm askung for is that the shadow be recalculated during the action. It would certainly be processor-intensive. But such and option should be available for export, where each frame of the build is calculated separately.

the shadow is rotated also, as if the light source moved. Is there a
solution for this?Duplicate the image, move the duplicate behind the original, give the duplicate a drop shadow. Remove the drop shadow from the original, and rotate it - the duplicate will not move and will therefore keep the original light source shadow.hth;
