Wire don't have copper in it. The coinage does. I do know a couple of old timers who used silver coin with a wire lead silver brazed to the back, but I won't go there until I can't get pure wire any more.

(Edit note: US coinage, which is what those two old codgers were using, has ten percent copper in it to harden the silver for handling in circulation. Those coins are going to put copper into the solution, but they seemed to do fine with it...)

So you'd like a bill of materials, and a step by step procedure for this. Here it is.

For a vessel to hold the water, I am using a wide mouth Mason jar of a quart capacity.

For electrodes I am using two coils of 16 gauge silver wire that I purchased about two years back. The pieces were originally five feet long. They're down to about a foot on the one coil, and a foot and a half on the other.
These were wound as two coils, one clockwise, the other counterclockwise to give surface area and paths to and from the electrodes through the solution. A lot of what it accomplished was to grind off particulate silver flakes that are now on the bottom of the mason jar. I'll likely harvest and recast the flakes when the wires become unserviceable as electrodes.

The electrodes are hung on opposite sides of the jar mouth. A quart of distilled water is added to the vessel, and the alligator clips from the power source (aka the wall wart) are attached. Make sure there is no contact between the electrodes. Plug in the wall wart and check that you have power. Then you wait.

I'll post the step by step pics for this tomorrow. (Edit note. It's going to be Thursday or Friday before I can get back to this matter. I have some other items that have come up and are taking precedence. )

You want between 28 and 36 volts at half to three quarters of an amp. Much hotter voltage and you get excessive flaking from your electrodes. I'm running 32 volts at six tenths of an amp. I'm getting fairly large silver particles with this level of power, but the larger pieces of silver tend to embed in the scabs and kinda help keep things from infecting.

You're working with three variables when you start working with particle size. Voltage is one variable. Lower voltage gives smaller particle sizes, all other things being equal. It also gives much slower formation of particles, so a batch takes three to five times longer to make. Electrode surface area is another variable. The diameter of the wire is a thing that can effect particle size because the electronic pressure is a factor of the surface area. Third thing that can affect particle size is water temperature. I've made this solution in a refrigerator, or on a counter on a frosty morning, and gotten smaller particles than usual.

I was talking about US silver coinage, not something that's .999 by specification. Those guys were using silver half dollars and quarters, and them for sure and certain have ten percent copper in 'em... I just don't have great desire for copper in my colloidal silver solution.

That said, Branch, a silver dollar size coin of .999 metal would make one fine electrode. The surface area would be great...
