My collection of English pennies spans a spectrum of shades ranging from shiny new copper (a bright amber orange) all the way to antique bronze (a dark chocolate brown).
Uniformity, and hence interchangeability, are therefore a problem.
I have various sorts of gaff sets that thus cannot be combined with each other, due to the stark mismatches in the colors of their copper aspects.
Obviously I could easily render them pretty much all the same with a quick vinegar and salt bath, but I really don’t want the default baseline of all my English pennies (especially the really old King George ones) to be bright and shiny.
So instead, is there a way of hastening the all-too-slow accumulation of that rich brown tarnish/patina on my shinier copper coins?
