All pre-1981, and yes it’ll turn you green hahah

The mechanics of it are rather interesting! It’s actually tiny bits of copper rubbing off and getting embedded in your skin, where the moisture causes them to quickly patina from orange, to brown, to green. The same thing happens when you do a lot of grinding or filing on copper; your hands get covered with bright copper dust, and then maybe an hour later they’re a sickly green.

Skin acidity has something to do with it as well, I know folks who have little to no reaction meanwhile half my finger is green when I wear these to bed.

Copper has a low enough melting point that I’m able to just hit it with an oxygen-acetylene torch and turn the pennies into a solid little blob. Then I hammer that down to a somewhat regular size and shape that’ll fit in my rolling mill.

On this particular ring I ran either side through the mill while leaving a bulbous lump in the center. I was originally planning to set a moderately larger oval ruby in it, so I needed as much metal for the head as possible.

From there it was just minor shaping, setting the stone, and a long stint on the buff. The slanty body lines and slopes on the top are actually an artifact of the rolling mill step. The mill is older then me, and likes to consistently cockeye your stock to the left. But consistent angles make for pretty geometry!
