Question, Battara, on this dagger as well as others daggers/knives that I have with ivory handles I use Renaissance Wax on them, will that protect them from the effects of ambient sulfur?

First: Sorry about your coins. Sulfur also reacts with silver to make sulfur oxide on the silver - also known as tarnish. This also happens on copper to produce copper oxide which is green (and poisonous) (lots of copper in brass and bronze).

Second: Renaissance Wax will protect them since it seals the ivory (also wood, steel, etc.). A very good question.
