Yes, that half dollar has been dipped.
I have always speculated that a large number of silver coins have probably been cleaned or dipped at some point. More than I like to think.
The problem with dipping is that it actually removes metal from the coin. Done too much and the luster will disappear leaving the lifeless blast white coins that make most of us cringe.
Here is a thought experiment for you. Can you tell it was dipped? If he had done this before you saw the coin (that is, you did not know he dipped it), would you have still bought it?
I know that I have coins in my collection that were dipped. I bought them a long time ago, before I knew what it was actually doing to the coin (therefore, I did not object to it). The coin dealer did it right in front of me (pulling coins from a collection he just bought and selling them to me). At that time, I honestly thought he was doing me a favour.
I look at them now and wonder if it is that I cannot tell they were dipped, or if it is that some or all of the other coins in my album were also dipped as well. It starts to blow my mind, so I try not think about it.
As I have said before about many things, if I cannot see it, then it does not affect me. But that is just me. So, I am not advocating the practice, nor am I saying that you should buy the dipped coin. I am just giving you a point of view to consider. If the coin still looks good, then there is no reason not to buy it, if the price is right.

I wouldn't have purchased it. As soon as it goes near a dip/cleaner/rag I'm outta there!

$40 is a good price for the set. Unfortunately lots of those early proof sets have spots. You're not putting a proof in the 58 P slot are you? That's like putting a satin finish coin in.  I need to find a local coin store. I pretty much buy everything online or over the phone. |

Coin Dip, aka Jeweluster or E-Z-Est is a dilute solution of urea and sulfuric acid. In skilled hands, a coin can be dipped with no traces left of said dipping. In less-than-skilled hands, dipping will result in a ruined coin with dull lifeless surfaces. You have to know when a coin can be helped with a dip and when a coin can be harmed by a dip, the former is much less common than the latter. Dipping a coin with concentrated toning spots or heavy overall toning can result in a rough pitted area where the toning was due to excess metal being removed. Dipping is best for coins with light but unattractive hazing or toning and it sometimes works well for removing old fingerprints that acetone will not touch. Dipping is NEVER advised for copper coins, unless you like them to be shades of pink or orange  I admit that I have dipped a few coins in my time but I take a large measure of precautions when doing it. A coin is only dipped for a few seconds and sometimes the dip is even diluted. Once removed from the dip, the coin gets a good swishing in a buffered solution to neutralize the low pH of the dip and then it goes into Milli-Q purified water(distilled is also fine) to rinse off the buffer. The coin then gets a final rinsing with pure acetone to remove all traces of water. Edited by biokemist6

Well, the "spots" were near the rim. And " I " can't tell that it was dipped. He did it only on the affected area there near the rim, not the whole coin, and only for a couple of seconds...and then washed it off and carefully blotted it dry. There was no "toning" at all on the coin.......just the dark spots that I mentioned. If I didn't know it had been dipped.....I am not expert enough to tell the difference. And the coin does look good, except for the pitted area(s) near the rim now. Quote:

Bio..... ...... JB....... I will put up some pics of this.....just "price-wise" I will have to live with this coin (& set) regardless of how I feel about it. But I hope, at least on aesthetic appeal.....the majority opinion will be a good one !I never stop "learning" ......that's for sure ! .....  Edited by eaglefoot

 ..... ..... Yeah that Satin Finish vs. Biz. Strike thing will be/is just MADDENING when you think about it ! ....  I don't know how folks can just "block out of their minds" this issue, and continue on with sticking in Mint Set coins with that special finish in the holes where Business Strikes are supposed to go ! ....  One just cannot "pretend" that, since 2005, it's the same coin in there ! It doesn't look like they're going to get rid of the Satins anytime soon now either....with these new biz. strike Sets coming out for the Parks Qtrs. ........  ......Lord help us ! ...

eaglefoot...my experience is this:
when I trust my gut instinct, sometimes I have genuine success; sometimes I make genuine mistakes....but I get genuine (and meaningful) lessons...and, so far, no one's died because of it !
:)
When I second guess myself or dont go with my gut instinct or dont listen to the answers I initially heard, things seem to get distractingly complicated.
Two general (not black and white) wisdoms I try and remember:
1. If I have to ask, the answer is "no."
2. If I'm having the conversation with myself, at some point, it's time to have it with someone else.

Yep ! ......I'm always learning.....some "good" lessons....some "bad" lessons. Everyone goes through this process I think.....you just hope that when you come out on the other side years later, that you've become a seasoned veteran "old-schooler" with a lot of wisdom and make "fewer" mistakes and bad purchases ! ... My Dad took our "company" camera home !! He told me he would bring it back to the office ! Seriously ! ...... |

I suspected that some of the Proof and Silver Proof Sets I bought from ebay was cleaned before they sell them as BU. Jbuck & Biochemist, can a cleaned coin be detected easier by stronger lens or even a microscope? There is one microscope that can be hooked to computer to take a picture in the screen and store it in the hard disc, that I considered. I am willing to invest the money if it is make it easier to detect. Oh boy, this is what I am afraid of, I am going to be a perfectionist, looking for the best collection. I promised to stop at UNC, period, when I started this US collection. |

The closer you get, the more you can see; so the short answer is yes. As what to specifically look for, I cannot offer much advice since I usually do not go beyond personal eye appeal. Since I never intend to sell the coin, I always try to keep in mind that I am the one that has to be happy with it.
This may change as I get down to the key dates in my albums, since I will be making much closer examination for authentication purposes.
