Over time my Morgan dollars started turning purple and rainbow color. I want to clean that pesky contamination off. I tried using sandpaper and tried scraping it off. On another coin, I used windex. What do you guys use?

    Power washer - 3,500 psi works well.

    Sandblasting frosts them up real nice. ;)

    Glass beading would even out that pesky cartwheel.
    Media blast with plastic pellets might be the ticket.

    Well, I use a belt sander, Then I buff them to fine finish. Thats will do the trick, then sell them on Ebay as MS67!

    Rock tumbler, heavy grit.
    Don't forget to check on them within a couple of weeks.

    Steel wool works wonders

  • Teeth whitening toothpaste with microbeads, if you can find it. They're getting hard to find!

    Well you certainly wouldn't want to use an abrasive object like sandpaper or toothbrush as that will damage the surface.

    Try a chemical dip/bath instead. I recommend nitric acid overnight.

    Why bother cleaning them? I thought your stance on Morgans was that they were the biggest scam in the hobby.

    Great. We needed another troll. :#

    Put it in the microwave for a couple minutes, but make sure you have a welding helmet on if you plan on watching it. B)

    Love the 1885-CC Morgan

    Seriously, over 50 years ago one of my boyhood friends was convinced that he could improve his silver dollars (he had some good ones like the 1889 CC (and the 1903-O before it became common)) and make some real money. He lived with his aunt who was a doctor and she had connections. He borrowed an ultrasonic machine from their dentist to clean the coins. Last I heard he broke the machine and his dentist was mad at him.

    That's the last time I saw him. Any guesses as to how the coins would have turned out?

    exactly, why else would they sandblast dies?

    if the mints can use that process to take bs dies/coins and turn them into amazing matte proofs, why can't we?

    Ajax works wonders.

    Throw a coin enough times, and suppose one day it lands on its edge.

    Says not use on silver but what the heck, go for it.

    If it's really gnarly crud, I put the Morgan in a bench vise, tighten the vise as much as I can, and go after it with a sharpened cold chisel.

    I’ve seen Sweet accomplish this on a couple occasions. They turn out real nice! I usually just use the old fashioned phosphoric acid with a Brillo pad. Nothing shinier!

    I can't believe people either fell for this or were just so bored, and thought they were SOOOOOO funny, that this thread is still going.

    I've been told I tolerate fools poorly...that may explain things if I have a problem with you. Current ebay items - Nothing at the moment
