My First Coin of 2024, Julian Double Maiorina

That's one of the reasons I found this coin (and where it was minted specifically) so attractive! I remember hearing how he visited Antioch and did not get along very well with the people living there, particularly since the East was already increasingly Christian by then. He even wrote a satirical essay, The Misopogon or Beard Hater, in response to the people of Antioch. The coin I have very well could've been held by one of his naysayers who examined it, or spat on it, with derision. A great piece of history all around!

These aren't secret methods. Using sodium carbonates to treat so-called "bronze disease" has been common knowledge for generations.

If you're skeptical and want to know what scientists have to say, you don't even need to go to the library or use a professional/scientific database. Literally just google it: Sodium Carbonate Treatment Bronze Disease.

If you want scientific papers to appear higher in your results, add the word "abstract" in quotes to your search. (Note: Some results will discuss "sodium sesquicarbonate," some "sodium carbonate," some both. They're all relevant.)

Or go to JSTOR.org and search "bronze disease" and "sodium carbonate" or "sodium sesquicarbonate."

It's not really reasonable in coin forum to demand that people back up their own personal experience (or @Victor_Clark 's case, professional experience) with scientific standards of data collection or whatever.

Especially since you're the one who works in the metals conservation field. If you have knowledge that this very well-known and widely practiced method doesn't work, by all means, please share. I'm sure that would be useful information.

 

Fair points, all well made. I feel I may have come across as stubborn when the intent is not as such - my scepticism does not come from anything except curiosity and if anything I'm impressed. I'm not a scientist but I do always feel that showing one's working is important.

To bring all this back to planet earth - this is a nice big coin with a nice big cow on it

 

I have an example of the same type as the O.P. Mine is rough, and certainly isn't as nice though. But an upside of mine is that I bought it 15 years ago when prices were a noticeable bit lower compared to today.

Update regarding the BD: So I placed my coin in a cup of distilled water for a week, used a toothpick to get rid of the green stuff, changed the water every few days and here's what it looks like now on the right. I just finished blowdrying it and I'd say it looks good to me unless anyone with more experience has any tips they'd like to offer. I haven't seen any green powder accumulate all this time since placing it in the distilled water and I'll be sure to keep an eye on it over the next month or so.

 

The BD is still there

 

Where is it? I put the coin back in the distilled water and will continue to periodically check on it.

That's the "before" photo

 

That's the before picture on the left, unless there's still more specks on the right? In any case, I've put it back in the distilled water for the time being.

(I saw you edited the comment, but I can't delete mine).

 

That's looks good just make sure to keep a very close eye on it because it could come back. But a gentle start isn't a bad idea, especially since all that's visible is stuff on the edge

 

Sounds good, I'll give it another week in the distilled water.
