The real problem concerns what is causing the dust to find the coins in the first place. Chances are your worst enemy is static electricity which is charging up the coins and turning them into dust magnets. Wiping them will move the dust particles out of sight for a moment, but will also increase the charge so that by the time you have recomposed an image, new particles have settled in.

It helps in some respects to shoot on a black background which, counter-intuitively perhaps, will show the dust more easily. But editing a uniform black is comparatively easy.
