Earlier Steenblik Coils

Anticounterfeiting currency is one application.
You take a piece of rock with fine detail on it. Fossilised chalk or diatomite or such. Gild it using gold/mercury for a conductive surface. Electroplate a hard metal like tungsten or chrome on it. (electrowinning most transition metals is easy) Dissolve the rock using vinegar or lye, and poof, you have a paper printing image that isn't going to wear out any time soon.

I've never heard of this technology before, and it hurts that I never figured something like this. It's a different kind of tech approach, and maybe we would have a more interconnected Med. culture due to the rise of denser cities, and higher trade.
