Anyone have experience with that?

Just for getting some clearance in this:
Every chemist would tell you that it is never a good idea to use silver in a system which contains copper, nickel and brass. Having nickel or not doesn't make a difference. The only reason for the nickel flaking off is that it just is a thin layer. But copper and brass are corroding aswell.
If you have a look at this:
You can see that copper, zinc (brass is copper and zink) and nickel are very close to each other while silver has much higher worth (not talking about the marked price
Anyway, as long as you change your coolant very often (water needs to capture a specific amount of silver ions to lead to corrosion) and don't have a direct contact between your silver koil and the other metals you will probably never experience any problems whatsoever.
But if you leave your coolant too long in the system it will definitely corrode. It also depends on the quality of the different metals, means a higher silver (f.e. 999 silver) will lead to more corrosion and a cleaner copper will not corrode so quickly as cheaper not so clean copper...
So it's always risky to have silver kill koils but the risk can be minimized
