Bronze disease?
« on: August 21, 2014, 06:41:02 am »
Hey there fellow FORVM members!

I'm currently rephotographing my coins and while photographing my Justinian decanummium I noticed a little green patch on the reverse (below the exergue) that I'm pretty sure wasn't there before. Is it time to throw the coin into distilled water?

I wouldn't do anything yet, just monitor.  I've had coins that I thought had new spots and when I reexamined the  old photographs I realized they were already there.

Sound advice from Nick, i would wait a while before starting any treatment but keep your coin isolated. You have the photographic evidence now (this post) so take another look in a couple of weeks to see if there has been any changes.

Nice decanummion by the way.  Good portrait for the type and fully legible year.  Very interesting ragged flan.

Thanks! It's one of the first 'nice' coins I bought, so I'd hate to see it slowly die of bronze disease!
