Maybe there are coins inside one of the 'vanes' (aka 'paddles') inside the drum??every time we turn on the dryer it makes a really loud noise, like a drum roll.
I can't think of anything else that could make the sound you describe. The common parts to fail on a dryer will usually either make a squealing sound or just cause a slow thumping of the drum as it turns, like a flat tire.
