I wonder what the difference is between the different case metals.
What is exactly coin silver?
Is coin silver the same as Sterling silver?
What is ore silver, is it similar to Coin?
What´s the differens between nickel silver, silverine, silverrode?
Best Regards!

Ok I'll start.

Sterling silver is .925 fine silver.
Coin silver is .800 fine silver.
Ore Silver is not silver but a nickle alloy.
Silveroid, silveride, silverene, Alaska Metal, Nickle Silver, Ore Silver and all those others are the same. Nickle.

I am just going off of memory and I'm sure there are others.

Aaron,
Coin silver can have a number of different silver concentrations. All American coin silver, including watch cases, is 0.900 fine, the same composition as the old US coinage. European coin silver can be 0.800 (the most common), 0.850, 0.875 or 0.900 fine, depending where and when it was made.
Watch cases marked "Fine Silver" are 0.995 fine, essentially pure silver.
The Silverode, et. al. cases are a nickel alloy, containing, I think, also copper and manganese(?). There are also cases made out of pure nickel which are similar, but not identical to the nickel silver cases.
