Dipping coins makes one a coin doctor

This was the prevailing attitude from TPGs and board members about 15 years ago. I agree with the statement because there is no skirting the fact that one is diddling with the coins. You can't half-diddle, even if you call it conservation...the moment chemicals come out of the drawer, we got a coin doctor.

Oh and if you bought a coin with the intent to dip, you are definitely a doctor. Please convince me otherwise, I genuinely want to know why this part of numismatics took a 180 turn in such a relatively short period of time.

    Even 15 years ago on this forum there was a line drawn between dipping a coin and what was considered to be doctoring. There were some who disagreed, of course, but most people thought ATing a coin to cover up hairlines or even to feed the toning craze, moving metal around with tools, applying putty or other foreign substances was coin doctoring but using acetone or even coin dips like Tarnex weren’t really considered to be doctoring. MS70 was at first considered to be ok, but deliberately using MS70 to turn copper coins purple was considered to be AT to feed the toning craze and crossed the line. Over dipping was always frowned upon, but not really called doctoring, just that it was looked at as a bad thing because it ruined the appearance of the coin. But lightly dipping a coin when it was appropriate wasn’t really looked down on 15 years ago on the forums. People used to teach others how to do it so newbies wouldn’t over dip or leave dip residue on the coins and others didn’t brand the people posting about it as coin doctors. People used to routinely recommend dipping proof coins in acetone before submitting them for grading to lower the chances of milk spotting or to remove PVC too without others calling them doctors.

    So tell me just what the difference is outside of a different word. I am always willing to learn.

    To make things very clear I have been a Coin Doctor for close to 20 years if dipping is doctoring.

    The concept that properly dipping a coin that may benefit from said dipping is coin doctoring is a lie propagated by the major players in the market to limit competition.

    Or I'm just talking a pile of smack. You decide.

    Actually, just read what Mark says. He knows his stuff.

    Dipping = using acid to remove metal/tarnish (metal oxide).
    Conserving = using a solvent like acetone to remove contaminants. Leaves the metal untouched.

    I think people like to say "poof" because they have no way to add to a spirited conversation. I am loving all of the answers and they are helping me better understand the history.

    As I've said before, I think dipping is okay to remove surface crud that has formed on a coin. That's it.

    I just checked out this coin. The oxidation seems to tell a story that it has a natural patina. I do see members talking about dipping coins with plans to store them in folders with known sulphur contaminants. "just to see what happens" with the new tarnishing.

    It seems some would argue that dipping is okay but adding it to the folder afterwards is when coin doctoring begins? The new toning will not be original, the surfaces have been through a chemical and physical reaction to make it appear better, and the new toning will be "wild" "monster" and off to auction!!

    I seriously have no idea about this.
    When one acetone dips a coin to remove gunk and etc., I feel that it is not meant to deceive a purchaser to promote a higher sales amount. They are not doctoring the coin. When the coin is sent in to a TPG, they determine the grade. If we all know that if there were a way to remove fingerprints on a coin that it would grade higher.
    Please educate me.

    I really appreciate your perspective, especially the part about intent to gain a larger sales amount But what about dipping to improve the value of one's own collection...the intent to gain value of the coin is still there. We may be getting deeper into the ethics behind conservation/doctoring/cleaning. This thread is helping me with lots of insight, so thanks to those who responded with valuable information.

    “Coin conservation is the stabilization and removal of potentially harmful residue on the surface of a coin.”

    Guilty as charged.....bought a slew of brown box Ikes, years ago. All hazy and ugly (no toning, proofs). Dipped them all in MS70/Distilled water (50/50). All came out beautiful. Put away for several years and then sold off and still looked great. I did not consider that doctoring but it surely was. The result was excellent and they coins looked as minted. There are a few times that a quick dip is beneficial. I'd never dip something not modern though.

    @MFeld and I both served on a special PNG task force to create a Coin Doctoring Definition for industry-wide use.

    Not hobby-wide.

    Purists and scientists can disagree with it. John Albanese, with Laurie Sperber's approval, placed me in the group as the resident conservationist cum coin-doctor and practical chemist.

    I side completely with the scientific basis of Mark's definition of (not simplistically, but for simplicity's sake) dipping in acid as "cleaning". One micron of skin lost and the skin is no longer "original". Neutron-microscope confirmed o:)

    If you want some hi-falutin' about semantics and what the industry has already accepted vs. moral probity and intellectual rigor, have at it. Perhaps only @Sonorandesertrat will be able to laugh at the sub-atomic nature of the debate. You should hear us go on about conservation and the conservative application of cavitation :p

    There is a Genuine/Details slabbed coin at GC that is labeled "Whizzed". Anybody collect whizzed coins? I bid on the slabbed Genuine/Details coins that only have "Cleaned" on the label. Nothing else. Great older coins on the cheap that would be out of my budget otherwise. I'm looking at nine coins from 1854 to 1927. Six of them older than 1900.

    I am in the dipping is a form of doctoring camp. It is done to change the appearance of the coin. I am not against it and in past collecting have probably owned a few dipped WLH's and SLQ's. There are different degrees of doctoring and have changed over time. When my father collected coins in the 40's and 50's cleaning was not as offensive as it is now. Who knows where it will be in another 50-75 years? Maybe dipping will be a no-no then. Time will tell.

    I had a dealer tell me once that he hated to dip coins but if a coin had ugly toning it was impossible for him to sell so he had no real choice but to dip it. I wonder how many here who are against dipping any coin would pass on buying a coin because it has ugly toning.

    Mostly agree, and perhaps things have changed in the last 15 years…because I once received an email from a person with an historical sounding name, who worked for our hosts, specifically soliciting my silver dollar business ‘if you don’t have time to dip them, we can do that for you.’

    The Colonel and Mark would know, but my memory is that the Task force in the end could not agree on a single definition.
    Some forms seem additive - baking, gassing, moving metal. Other forms are subtractive - dipping, cleaning, whizzing.
    I have always preferred the term messed-with to describe a coin. A very inclusive term.

    The "task force" did not reach agreement, nor did it have to. I passed along a four-page report with many details that was digested by the "statement committee". The "dipping issue" was never resolved via debate. It had been resolved 35-40 years previously by the market.

    The world is one big grey area, but I find the need to add the above phrase to rationalize dipping to be interesting.
    For the record, I have no problem with dipping as a concept.

He said the same thing as above, except he seemed to take pleasure in dipping coins. Among some other odd techniques, right in front of the club members he took (what I thought was) a reasonably toned, AU seated half, said it had been in his shop unsold for a few months, so it was time to change its look…broke it out of its 2x2, dipped it to a bright white, stapled it into a new 2x2, and then bragged that it would now probably sell within a couple of weeks. I thought the whole “show” he put on was disgusting and I’ll never forget it or him. True story.

All had golden/brownish rim tone over the luster, from long term album storage. None sold, and I was told they were ugly and asked if I’d gotten them from a house that had a fire. And no, I didn’t dip them afterwards. I held them for more appreciative folks.

    There was a coin dealer several years ago, John Gervasoni from New Jersey, who many people thought might be "connected". I always liked John, and finally asked him "John, have you ever had anybody "whacked"? He looked me straight in the eye and said, "I've NEVER had anyone whacked...that didn't deserve it...."
    Personally, I've never dipped a coin that didn't deserve it....
    Some coins just need to be dipped. I've always thought the definition of coin doctoring is ADDING something to the
    surface of a coin, not removing something.
