Not clean and shiny. Not irridescent (although thats nice too!). Not 'perfect' in any conventional sense. I'm talking about when some black hoard patina or deep toning and exposed/ worn high points on a silver piece interact in such a way that the details just pop. Sometimes that look is totally natural but often there is some 'skillful cleaning' involved. Bronze coins of course can take on a huge array of colors and combinations, adding immeasurably to the eye appeal and overall character. Here are a couple of coins I could not pass up for the above reasons. Please share your colorful gems! Greek, Macedon (Roman Protectorate, First Meris, ±167-149 B.C.)
