Sorry if my previous post may be upsetting to some and seem callus? Well this one will be worse: Really to use ancient coins this way - as if they have power .. while the vulnerable cling to anything when times are bad .. sad - lets not pretend there is anything that will help anyone. Mind over matter - I get it. It's comfort - when needed... and that is something for sure and something to be respected - But there are other "real" ways to help and comfort the sick that doesn't involve pretending these objects help in any way. Snake oil.
Thanks, now I have to go back to work on my Greek Mythology, the ancient version of the "Young and the Restless" IMO.
Let's end this path of discussion. Everyone's idea of religion may vary, but none , nor the lack of such an idea, is provable. So let it go as such is not allowed as a discussion here. Jim
(I know some may frown on this, but...) I've found the steel wool stick that is often/sometimes included in the 4/5-pack of Andre crayons very helpful to loosen up the sand patina. Lightly (very) brush the coin a little bit in a circular pattern, check it, repeat until desired removal is reached, and because it's relatively small you can focus on areas that may need it more, be them fields or devices. Like anything, in moderation--check often, stop before you go too far. Here's a pair of reverses I've recently used this approach on... Edit: and on this one (didn't even know at the start he was holding a mappa)...
Desert patina is impacted dirt. Washing the coins in water or any liquid is likely to loosen soil that you would rather remain. Mechanical cleaning (scraping, brushing, picking with a tool of any sort) has the advantage of allowing you to stop when you get to the point you want rather than going to completion.
I apologize, @desertgem! It was my post that initiated this. My apologies also to @TypeCoin971793 for disrupting his excellent thread.
Many of the coins in my Judaean collection have the desert patina look or at least a sandy appearance. As many of you know, I occasionally submit my coins to NGC for slabbing (mainly ones that I plan to sell at some time in the future) Anyway, occasionally, I am informed by Mr. Vagi and his superb staff that my coin has been re-patinated. This one came back with no such notation so I’m of the belief that it has an authentic patina.
