    Laser coin restoration video

    Thought you guys might find this interesting. I can't tell but it looks like it would butcher a more modern coin? I suppose it has value if you were trying to touch up 1000 gnarly wheats in 10 minutes or less! ��

    "ready to be varnished"...lol But then again, I'm not all that squeamish about cleaned coins....original is nice, but if there is no other choice...what the heck.

      Eowch! That left some really weird lines on it.

      I'd like to see that with a coin that would be a BU were it not for verdigris caked on it!

        There goes the patina and the value, if any. I can achieve that result without a laser.

          They are calling this 'restoration'? I see it as damage . I think the dark brown color is what makes these older coins so special.

            That is damage alright... The laser burns what it comes into contact with... That is why jewelers use lasers to engrave high value diamonds... There is no way to remove the laser engraving with out damage to the stone... If we could zoom in on the coin in the video there would be microscopic metal blobs on the surface... I could see the laser being used on a barnicle encrusted coin but there are other ways to do that... They just take longer!!!

              I read somewhere about how NGC's restoration service removes a "microscopic" layer of metal yet still leaves the luster intact. I always wondered if they chemically dipped the coins or incorporated a laser perhaps? I'm far too ignorant to pass judgement on anyone's methods. I'm just curious. One of the main questions I have is how deeply could you dig into an UNC coin and still have any remaining luster derived from striking at the mint?

                Original is the call for me. As a historian, the patina is what gives antique and collectables their charm. Even a BU wheat cent with the original thumb print can be intriguing to look at.

                  Not sure how they would do that... That would be interesting to find out tho!!!

                    Just goes to show you how quick we are as a species to misjudge others. We spent our childhood being taught that aliens with lasers were trying to kill us. But all along they were just peacefully trying to show us how to restore our coins!

                      I think it means they carefully dip the coins in chemicals or dips made for coins. Dips remove some metal. The dip changes color from the metal. If you dip CN coins then copper in the same dip you can see the silver color on the copper or vise versa. (so they only do one metal type the change dip)
                      If a coin is over dipped then the luster is messed up but if they do it right it may improve the coin, they know how long to dip and they rinse well so "most" coins survive their restoration without being messed up.
