There is a special grade for that coin. MELT BUCKET  . Looks like it has been whizzed then polished with brasso  |

Quote:My understanding of dipping is it wont affect the lustre but from comments here it seems as if people think it might. Acetone only removes organic grime/toning and as the lustre is inorganic I would have thought it wouldnt be affected  the americans seem to do it heaps from what I've seen on this site.
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 Edited by rbarat

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.

Hi Bellyflorin,
I apologize if that post come off in the wrong tone. I'm by no means an expert, and I was just braindumping my last couple of months of obsession! :(
Regarding ANDA you are correct there is no reference to cleaning or dipping, my reference was just specific to where lustre may be seen in an aUNC coin in the aUNC section of the guide.
PS: Don't keep your opinions to yourself. I'm sure everyone here is more than happy to help us.

Klaus Ford wrote the anda grading standard. It should come as a surprise to noone that the effect of cleaning on a coin isn't mentioned in that standard.

I never knew Klaus wrote the ANDA grading standard...wow, that sort of baffles me. So, does that mean we're trusting a guy in glasses...just taking the piss out of people wearing glasses.

Firstly, I would say that ANDA is a group that exists to support its members - namely dealers, not the wider numismatic community. Secondly, on the issue of cleaning, while I understand that many may view it to be ethically dubious, we do need to bear in mind ancient coins, and the re-sale of coins that have previously been cleaned. Note: in stating that, none of the above changes my personal view that the use of silver dip (in an attempt to increase the sale value of a coin) by a dealer is unethical. |

No Clean. No dip. Nothing.
