The Coin Toss assembly was not originally finished in Zinc Dichromate, as John Pop has suggested (well mine wasn't). I did see the actual finish on some nuts and bolts and it is a dull finish with a rainbow effect when held up in the light. The finish on the coil toss ramp is likely nickel, then brass with a clearcoat. But no one can say that this is EXACTLY what was done. Whatever method was used - it was cheap and nasty.
I don't have any real options that are feasible. GOLD plating is too expensive as is Brass and there is no guarantee that the inside of the assembly will "take" the bath process. The brass method will cost over $100, and most places didn't seem keen.
The main ramp will be replated in a "gold finish" - obviously not real gold, but I saw some of the gold plated parts hanging in their shop and it looked amazing.
I'm still not entirely convinced, but I didn't do anything with the coin toss assembly, but the main ramp will be re-plated.
I can have both Chrome plated, but I wanted the gold finish.
If you don't mind doing a bit more running around, these guys in Melb do Gold Plating
http://www.masterelectroplating.com.au/Not sure where they are in relation to you, but I do know they will gold plate ramps, assemblies etc with a quick turnaround time of about a week (a friend in Melb has had pinball ramps gold plated with them)
As said in my earlier post a couple of pages back, if you are only gold plating a wire ramp (smaller surface area) it should be a reasonable* price, but once you get into large surface area items like the coin toss assembly is when the price will add up.
*reasonable being a relative term.
