So I had bronze coin (full of clay) in a distiled water bath for 1 day, I took it out and cleaned it (with a toothpick), now the coin even after drying several times seems a lot darker, can I by any way revert this? Will it help if I leave it in the sun?
Rest in Peace

This is not my expertise but was the distilled water dark and dirty when you took the coin out ? Maybe the coin was stained by the dirty water and not properly rinsed .

The dirt may have given it the lighter color. Now that it is gone you see the true dark bronze color. Leaving it in the sun
exposed to the elements would probably darken it even more. Bronze isn't like hair, it doesn't sun-bleach.

Well I have a before and after photo, but one is from the seller the other is from my camera (a really bad one and poor light). Even taking the light colour of the clay in to consideration the bronze itself seems darker.

Did I just ruin the coin? Is it better or worst?

I think Conder101 is right, the dirt was lighter in color. That said, I think it looks better now.

I also think that it looks better.
On this subject, I have some cheap roman coins that I am cleaning using distilled water, brush and toothpick. The dirt seems to be gone away, but some of them have a very dark tone/patina, much darker than this one. Plus the details are soft and I cant read it. Is there something I could do to make the tone lighter without damaging the coin?

I entered the thread thinking I was going to see something truly horrific. Quite the opposite it appears. I think the coin looks much better. Very nice job

I too think you ended up with what that coin should look like. Glad you didn't mess it up with a toothpick.

Looks like you dissolved off a lot of old mud. If you want it to go back to that, dip it in a diluted mud solution and let it dry. Repeat to get desired coating thickness.

I'm thinking that if it came off that easily in DI water, then it wasn't real "desert patina". It was just mud. Presumably from an attempt to artificially create a "desert patina" look on a coin that was overcleaned.

I am certainly no expert but it looks much better to me without the grime on it as well.
