Generally speaking: -a fully plated gold board would probably be comparable to the gold edge category. -transformers are a mix of copper and ferrous material and they may add some value to lower grade boards but likely bring the value down on most grades. So it'll depend on the board and size of the transformers, but usually safe to remove. -copper is much higher value than a transformer so it'll benefit more boards than a transformer, but still will bring down higher grade boards -aluminum is less valuable than copper and not much better than transformers so it'll be about the same as what I described about them. -silver prices are up a bit, still it's much less valuable than gold and much more valuable than copper, so yes silver in boards still have a impact on value.
