Thanks for the tip :)
I usually never clean my coins, but this one needed a little ... dirt removal (what's left seems to be some oxidation).
Oh, I was wondering, how much a such coin is usually worth ? (to know if I paid too much or not)
Anyway, I like it :)

Soak the coin in acetone (pure - not nail polish remover with perfume). It should come off - NEVER use a brush because most brushes mark the coin and you will be able to see the effect under a microscope.  It might get off. But if its still there, just leave it the way, anyway the coin is a beauty |

I won't soak it completely, if I do something, it's just to remove the big black stuff after the date :)
The rest is perfect :D

Go at the area in question VERY cautiously with a toothpick, taking care to not rub (scratch) the surfaces with the loosened dirt, as was mentioned by WestwoodArms... A traditional similar method for spot removal is to use a rose thorn.
In concert with the acetone (remember, keep acetone well away from any flames... and it will eat at most plastics so use a glass or ceramic bowl), some very VERY careful picking at that area should remove most of it. I also hate a distracting spot like that on a piece and would also try to remove it, and the area in the reverse denticles which is safer b/c it's more well-hidden... Such careful spot removal isn't going to kill the coin, as the piece had/has slightly "conserved" surfaces anyway. In general, however, remember that an area of obvious caveman scratching can look even worse than a spot, especially if you know how it got there.
By the way, ditto on what Bob and Westwood said... don't attack the whole surface with a toothbrush or similar, particularly because you will rub the loosened dirt back across the surfaces and leave minute hairlines. That kind of technique should be saved for heavily corroded/encrusted salvage finds where you won't hurt it any more than what the ground/sea has done already...

Nice addition, Mathieu! It's my favorite eagle design, as well.
In terms of "cleaning", I usually do what was already suggested before - acetone soak and gentle pokes at the spot with a toothpick. If it doesn't come off right away, I just let it sit in acetone for a while longer.

Acetone works well :) I didn't wanted to remove the patina, so I tried to not put the whole coin in it. The result is nice, and the toothpick helped a lot. Here are the new pictures :   |

It came out looking even better. Did you buy the entire pot of 40 coins?

Well, the coin was made in 1833 :) It's quite old. I didn't bought the pot, it was on sale on ebay, and I noticed it late :( I missed other crown sized coins I was looking for, but managed to catch this one. |

Hard to price these, but I no way specialize. Someone who wanted to put together some kind of set might drop US $80. If I liked the coin in hand I would drop $60, but I don't collect these specifically.

OK, that's about what I paid :) Anyway, I now have a nice early zacatecas eagle - which is what I wanted :D I'm not looking for other south american coins after they left spain (maybe for mexico I should look for an Iturbite crown ...) Like the one in my avatar here, which has a very nice design :) There was another one from this lot on sale yesterday (the seller was auctioning the last ones from the "treasure"), I think it was a bit better than this one : http://cgi.ebay.com/ws/eBayISAPI.dl...250964138305 |
