This is by no means precise, but I found it a good place to start.

I like that chart. The charts I have for the manticore are pretty much useless because they clearly show you need to dig everything except a pure iron tone or you will miss reales, gold and platinum rings and chains, silver chains, quite a few older coins etc.
