Orichalcum Coins that show their color

As I understand, most sestertii were minted in orichalcum, a sort of golden-colored bronze alloy. When fresh, these coins would have shone bright gold, not unlike the "golden" dollars of the US since 2000.

Most sestertii after 2,000 years have a variety of patina, coloration, or deposits that obscure the original striking color. It is unusual to find one with anything close to its original color.

I have this sestertius of Trajan, which started off with encrustations and oxidation out the wazoo. After a gauntlet of chemical treatments, I revealed the original, shiny, brassy color.

I would absolutely love to see your coins that retain their original coloration!

Apparently, all Imperial sestertii were orichalcum, while during the Republic they were silver up until Augustus. Only Marc Antony made any in bronze (if I’m reading it right). Much easier than dupondii and asses, which look the same and can be either orichalcum or bronze.

Sometimes I come across a yellow Provincial.  This chunky one from Antioch struck for Claudius is very brassy (thanks to an overly-enthusiastic cleaning):

And its distinguished pedigree (beyond eBay, I mean):

Some years ago I bought this remarkable series of orichalcum coins from a venerable old seller, whom I have known since I was a boy of 15. Now in his eighties, he still has his little stand at coin fairs offering remainders of his once grand collections. When I came home, I noticed his coin holders all carried the same code: "Jakob Istanbul Dec. 1974." Apparently the four all came from the same seller, bought (at the day I acquired them) 43 years earlier from a coinseller Jakob in Istanbul. They probably were kept together for some time, or maybe cleaned injudiciously together, to account for the same accretions of milky and vermilion (or red cabbage) colors, not to mention the fresh green pea spots.

Here's a Galba sestertius with patches of the original orichalcum color amid generally brownish black patina, which at one time probably covered the entire coin.

Galba, orichalcum sestertius, 68-69 AD. Rome. From Roma E-Sale 86, lot 931.

RIC I 456

Julius Germanicus is truly the man for the shiny sestertii 🤩


Here are some Sestertii made of pure yellow Orichalcum (it is noteworthy that unpatinated Sestertii from Marcus Aurelius to Septimius Severus and from Severus Alexander to Decius usually consist of a more reddish alloy due to an increased content of copper and a reduction of zinc, while those of the later soldier emperors appear darker and darker due to containing no more zinc but lead and other cheaper metals)
