I have a dumb dipping question.

PerryHallPerryHall Posts: 46,339 ✭✭✭✭✭
I don't believe in dipping coins and I can't remember the last time I dipped a coin but every once in awhile one comes across a coin with extremely ugly toning that would be hard to sell in its current condition. My question is, after one dips a coin, should it be rinsed in hot water or cold water or it doesn't matter.

    I would suggest cold as hot may initially increase residual dip oxidation effects before it is rinsed away completely. Also, I use a mild dish detergent and wash it off THOROUGHLY. Might just be me but when I first experimented with dipping I found some of the coins to retain dip in devices and lettering where it can eventually cause problems itself as it is an oxidant.

    Rarely use it these days, and have recently been happier in conjunction with the famous Taco Bell napkins to get a decent new skin on the coin - none of those obvious AT colors going into the neon pink, green and orange that now are consistently called "NT" on these boards.

    7Jaguars---How about a cold rinse followed by a light washing with a non-abraisive liquid detergent such as Dawn followed by a rinse in hot water to get the detergent off. Obviously the washing would apply to a proof coin due to the danger of hairlines.

    Immediately after the dip I rinse thorougly under cold running water. I dissolve a couple tablespoons of baking soda into a saucer of cold water and then dunk the coin in this solution to neatrualize any dip that may be present followed by another thorough rinse with cold water, I then pat dry. Be careful not to rub the coin while the baking soda solution is on the coin as it can impart hairlines onto the coin.

    Soak, do not wash, the dipped coin in cold water for up to 30-minutes.

    Not exactly. They are brown in color and probably have a high sulfur content.

    Make sure you use Distilled water.. I have heard people with well water will leave spots and too much treated water will bleach it.. Hope this helps..image

    Wouldn't a long rinse with tap water followed by a quick rinse in acetone work? Seems cheaper than rinsing with a gallon or more of distilled water.

    Perry, I really don't know.. I have heard some people have terrible tap water that is full of chemicals that will take the enamel off of a persons teeth... So, a birdy told me always buy a gallon of distilled water and soak your coins in for no more than 30 minutes, but I wouldn't even leave them in that long.. Hope this helps..


    P.S. I have well water that is ok by EPA standards, but I know the iron content is ok and cal levels, I would never try to clean coins using my water.. I just had my elements changed just last week and both heating elements were caked with Cal all over. I advise anyone that has seen a up shoot in electric bills change your hot water heater elements once a year.. Already my electric bill has dropped 55 percent from just last month..

    too much work you guys,

    dip then a good rinse under an open faucet,

    then dry with a hot hair dryer.

    Complete process takes less than a minute.

    Heat encourages chemical reactions to intensify. Therefore cold water is the way to go.

    This process has worked for me:


    My process is as follows - wear safety glasses and ventilate properly:

    Grab the coin by the edge with tongs and lock them:
    Rinse coin under almost hot running water - this puts a bit of heat in the coin.
    Dip in EZEst - about 2 seconds. (You can always dip again)
    Immediately rinse in the almost hot running water - 5 seconds per side
    Rinse in a cup of distilled water - 5 seconds
    Rinse in a second cup of distilled water - 5 seconds
    Dip in ammonia for at least 10 seconds - this neutralizes the EZEst - ammonia is highly basic and will passivate the silver surface. (Longer does not hurt here)
    Dip in a third cup of distilled water
    Dip in a fourth cup of distilled water
    Blot water off between paper napkins. Do this several times to remove all water. DO NOT RUB. Blot only. I usually use three or so layers of napkins.

    Repeat if necessary.

    There are too many chemicals and sediments in tap water, use cold distilled water.

    It is fascinating to stand back and listen to all of the various suggestions.

    I'm not saying who is right or wrong. It would be only my opinion anyway.

    No wonder so many coins are screwed up, though.

  • sounds like a couple tests are in order, before working on a coin that really matters.

    Perry, I would do exactly as you suggest with the rinse afterward - I have had excellent results with this. Interestingly, unless tap water is really gross the only way it has caused problems for me is if it is left on the surface to dry. I tamp down my coins with a high nap white cotton towel = NO RUBBING (obviously).

    I'll bet ours would. You ever smell the sulfur water they have in South Florida? We have it here. Everytime ladymarcovan does the laundry and uses up the stuff in the aerator tank, I end up having to take a smelly shower. I'll usually use bottled water for a post-rinse dip, but have forgotten and used the faucet a time or two. The long term results were not always awful- sometimes a light goldish tone resulted, and sometimes none at all. Occasionally this secondary tone was blotchy or uneven, though, which is not good. I'll agree that one should probably used distilled water for a rinse.

    I've never used acetone or ammonia as a post-dip rinse, though I've used acetone for removing adhesive residue and paint and stuff like that on coins. I can imagine their possible benefits, I suppose.
