I’m not sure when they went from solid copper

1982

A friend said a local brewery has a hose packed with copper tubing. If they have a stinky batch that is used for the transfer to the Brite tank. It doesn't take much contact time, as Martin says.

   Mid 1982 to be a bit more precise, there are all copper 1982's and clad ones. All copper pennies weigh ~3.1g, clad ones ~2.5g. Tedium ad nauseum .

As a kid we always commented when we got a "steely" in change.

I have been looking into this further and it seems the wine makers among us have a solution. They use Reduless or Copper Sulfate.

Did the sulfur taste go away?

[BrewBama]

No. The penny has been hanging in there since last night but I still get smell and taste.

I found it interesting that one source stated that to practice detecting the Hydrogen Sulphide off flavor to add metabisulfite into the beer.

Great! 

That’s what I did thinking I was eliminating chlorine/chloramine. Instead, I think I shot myself in the foot.

If you used the correct amount at the right time, that's not what's causing your problem.

I normally use distilled water. This is a pandemic batch and the shelves were bare, so I used tap water treated with Kmeta.

I’ve brewed this base recipe dozens of times. The only other difference is Eukonot hops. Same yeast, same grist, same mash, same ferment, basta.

Since this has never happened before using my normal processes in over 100 batches, I am looking at an overdose of Kmeta as the smoking gun. Of course, I could be wrong and could have a serious infection.

How much did you use?

[BrewBama]

.3 grams Kmeta powder in 8.5 gal water

Doing math in my head based on memory (you know how that goes), that certainly doesn't seem excessive.

ETA:  OK, looks like one tablet, which is good for 20 gal., weighs .44 gr.  So you were a bit high, but not what I'd call over the top.  Martin, where are you?

[BrewBama]

I used 550 mg for my calculation.

Yeah, I see that now.  Different sources list different weights.
