Basically, gold plating has a general 'thickness' to it dependant on the karat of the gold, in this case you would have to know the surface area involved (tricky to work out due to nooks and crannies in the surface, but not impossible) and then you could work out the coating from here.

this is actually interesting, when would it decrease in value? when gold prices drop? or when the item becomes old and unwanted?
