Sound engineering - how to create an adequate coin drop sound?

Okay, one or two of you guys might think this topic is meant as a hoax - IT IS NOT!

As I am wiring my coindoor now, I realize that I have to think about solutions for little details. One of them is the sound of the dropping coins as the sound of them dropping on wood is like a V8 Mustang sounding like a lawnmower. If you have seen my project, you will know that I don't got a over/under coindoor - instead just an ordinary coindoor - but hey, it was only 1,- Euro on Ebay (and 12,- Euro shipping from Austria ; )

I wonder what material original arcade coin containers are made of and how they are placed (e.g. on the cab's floor or "floating" under the coin mechs) or how they look at all and what would be the best way (except of replacing it by a new and original coindoor) to make the drop sound more satisfying. Any solutions? I already looked on ebay but all I can find on our german ebay are coin containers for those modern day european slot machines...

So, anyone who likes to tinker? Any ideas?

Every US and Japanese machine I've messed with (other than candy cabs) has a plastic coin bin sitting in either a relatively tightly enclosed wood or sometimes metal (more popular on Japanese machines) housing.  The coin bin housing is entirely enclosed, save a slot for coin entry, and this does create a sort of resonance sound when the coin drops in the bin and hits either the plastic or other coins and bounces a little.
RandyT:

How about 4 pinball solenoids connected to the corners of a metal pan full coins that are triggered by a secondary coin drop switch going to a 24v relay, so that every time a coin triggers it, all the other coins are sent 6 inches into air ?

That should make enough noise  ;D

Seriously, though, even one solenoid popping the bottom of such a tray might give you a pretty powerful sound.

I thought the classics did have wood boxes. What's wrong with that sound? Otherwise use a bucket and fill it with coins. That gives you a more modern sound.

I just take a plastic tupperware and fill the bottom layer with quarters.  :)
