Once again you have proven me wrong, my friend. The cleaned coin is much better. And to think I recommended leaving it alone. Hmmm, makes a case for not listening to me, eh?

I was going to say leave the coin as it was, but after seeing the results after you cleaned it all I can say is wow. Great results.

I bought a pound bulk from an ad that showed a pile of white powder. A pound is a lot! Some sellers make the statement that you must be 21 to order because there are people who eat the stuff and they really should get the medical grade and a lot of advice from their doctor. I'll repeat that it is hard on bronze coins unless watched carefully. |

dougsmit, The details of the coin was great with the heavy green patina, but after the cleaning job, looks much better. You never know till you clean it, sometimes they don't come out this good....  |

wow, that coin looks great now ds....i wouldn't have cleaned it, but I'm glad you did!
I've had a few with similar stuff on them, one I damaged by picking to much ....the other I just left alone after my first mistake.
how likely is the edta to damage the coin?

Ummm, I still kinda like the "hue" of the green one ... is that wrong? However, obviously both versions would be great additions to our collections (and the "more" cleaned version does show a bit more detail) ... But geeessshhh!! => I just want dougsmit to drop the ball for once!! ... but it never seems to happen! => well played once again, dougsmit ... well played!!  |

Dirty ancients are an exception. Most come up out of the ground basically like rocks or gunk-covered and have to be cleaned to at least be identified. Cleaning, if done right, will increase the value of the coin.

I agree some of the details of the coin are now better in appearance. Had this object been a valuable piece at a museum or gallery and deemed in need of restoration they may have used the same or some similar chemicals. The difference would be that it would be done a fraction of an inch at a time, removing only what was absolutely necessary for the desired results and may have taken several months to accomplish.

I would agree that the 'after', in this case is better than the 'before'.
Couple of questions:
- From where would you purchase EDTA?
- Would Verdicare have done a better job?

See answer at 1:14 PM yesterday.
I have no idea what is in Verdicare or any other commercial product.
