A silver strike is one of the pretreatments that I was referring to for the proper adhesion of plated silver on copper. A silver strike is typically a very thin deposition of silver (fraction of a micron) from an electrolyte containing a low concentration of silver ions and high concentration of free cyanide as a complexing agent. From my experience these coatings do not produce a pure silver layer.
By the way, burning fossil fuels is not the only source of sulfur in the atmosphere. Sulfur is also released from the decomposition of sulfur containing organics and from volcanic activity and geothermal vents. So there is plenty of sulfur in the atmosphere, even in Canada.
