Quote: I have a question though. Could someone post some pics of dipped coins? I have a few coins in my collection which I have suspicions were dipped. Does a lightly dipped coin retain cartwheel lustre?
the coin on the left has been dipped see the diferance

Thanks for that trout  My ol eye's are a little dim but it does make a difference and after seeing that I'd say don't do it as it does take away from the coin a bit..less detail or something, just can't put my find on what..maybe the lack of patina as well

The florins are both technically great coins but the dipped one is nowhere near as lustrous as the undipped one. The dipping must make tiny little pits in the lustre and dull its appearance. In layman's terms the dipped coin is not as sparkalarkly as the untreated coin

Thanks trout  So dipping may cover surface imperfections but it gives the coin a dull matt appearance. That is useful to know. Quote: Acetone only removes organic grime/toning and as the lustre is inorganic I would have thought it wouldnt be affected enworb - by dipping we mean dipping in a silver solution to add a thin layer of silver to cover imperfections on the coin.

[quoteenworb - by dipping we mean dipping in a silver solution to add a thin layer of silver to cover imperfections on the coin.
][/quote] There are all sorts of methods employed in this nasty practice. Some people dip in jewel lustre to clean the coin and then dip in a silver plating solution to restore the lustre. If it is done solely to make the coin in your own collection look better for your own pleasure then good on you , It is your coin and you can do what you please with it. But if it is done solely to deceive a buyer then I think it is a very dishonest practice and should not happen

appleangel07, To me they look like they could actually be polished, which is worse than dipping because you lose the lustre and alter the original surface of the coin. Not very pretty to look at either way..

Quote:My understanding of dipping is it wont affect the lustre but from comments here it seems as if people think it might.

I did reply ranting about acetone but have just re red the thread and cottoned onto the fact that you all mean something nastier than that. Yeh dont do that Dipping in acetone won't affect lustre. It won't affect tarnish either, so it's not likely to do anything to the coin in the OP, and it's not likely what Klaus meant by the term. Dipping in acetone can be a preventative against fingerprint formation, but can;t help once the print has developed, as those prints have. Silver "coin dip" is typically a mixture of dilute acid (usually sulfuric or, in some mixtures, a substitute like citric or oxalic) and thiourea. Dipping in silver dip will remove tarnish and will, to a small degree, reduce lustre, especially after repeated dips or a prolonged soak. A "quick dip" might be perceived as harmless by some old-school dealers, but to my mind it's like smoking - "every cigarette does harm".
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis

Quote:What do you think of this coin http://www.ebay.com/itm/1927-Florin...em27c092011f . I am off to work now so I will catchup later. To my untrained eye : The reflections on that coin seem to reflect in the right spots if the coins was showing its cartwheel, and is consistent with the ANDA guide to grading for an aUNC coin, where luster should remain in the legends. As the coin is in a 2x2 the texture that is showing on the obverse appears to be the reflection of the plastic window in the 2x2 due to the angle of the photo, and not of the coin itself. The marks to the left of 1927 on the reverse are a little concerning though, however these could be the coin pressing through the 2x2 as the marks are above the left plant(is that what it is?) and the 1 in the date in which case there is no problem. If this was a coin I was considering buying, I would request a photo of it out of the 2x2 before making a decision. Has the coin been dipped ? I don't think so. Compared to Trout's photos, the dipped coins seem to have a balanced look, where as this florin does not. -rob

Hi rbarat ANDA hasn't got any grading guidelines regarding dipped or cleaned coins , well I couldn't find any ! , . You do need to look at each coin in the hand to be sure ,Yep sometimes photos just don't show the complete story, good or the bad points. I just had a look at the sellers other florins,hmm yep I will keep my opinions to myself ,as the right thing to do is to ask seller questions and ask for more photos.
