@hord, I'm interested to see how you progress with this thread. I have a couple suggestions: first take all pictures with the same background so that we can compare surface color. Second, take pictures in between each step rather than only at the beginning and end.

On this first coin, the surfaces in the after shot look a bit soft or pitted compared with the before shot, but I'm not sure where along the way this happened. Thx for helping us all learn as you explore this.

@Spence. I definitely have a hard time finding a consistently good spot to take photos. What you are seeing is probably graininess from me over editing the photo becuase of bad light. There are also very heavy metal flow lines as well which aren't really coming through in the photo, probably contributing to that grainy pitted look. Third, on the reverse, there is a fair amount of near microscopic cracking with dirt in the cracks giving it a slightly more pitted or dirty look. I couldn't figure out a way to get at that dirt without hurting the coin.

@John1 Thanks for the disclaimer. I probably should add a few words about the ethics of cleaning Ancients in my first post versus modern coins and why I feel that this was okay.

WOW, you did a great job.

I would call that a successful restoration. Let's see more.

Ok yes, there are definitely flow lines (as there so often are) on the obv. However, I do think that you got a bit more of a pitted surface, especially on the rev. It is all good though as a learning exercise.

A good result in my eyes.

Not having had any luck in cleaning coins I look forward to seeing more in this thread.

Phrygia, Synnada AE. Turreted bust of Tyche facing right.

For this one I soaked it in distilled water for almost two weeks before touching it. I then did light detail cleaning with diamond dust pins around the features.

HEED THIS WARNING: Usually I give bronze coins a slight once over or two with a bronze brush. I did that here but due to the encrustations basically covering bare bronze I ended up revealing more bronze than I needed to. If I could go back I would have been much more careful with the brush and in general I will hesitate brushing encrusted coins.

Abbasid dirham, 93% silver. 2 minutes in a sodium thiosulfate solution. Horn silver completely gone. Probably should have soaked for only a minute. Some of the toning was stripped with the horn silver but that's the cost of business. I think it is an improvement for sure without the black.

Watching this with a keen interest. It is something that I am just starting to dabble with.
The second and third coins I probably would have been happy with personally. But the results are an improvement.
Cheers
