Wipe the patina right off. That is cool though, science more like star wars everyday. Make one hell of a weopon. Light saber, "I'm your father" Or something like that
Lasers have been ysed to smooth the surface of gold coins for several years. I'm sure they work on copper also to remove spots.
It really is cool. I can vividly remember a demonstration, while in highschool in the 70's, of laser technology at the time. They used a machine the size of a torpedo to put a tiny spot of light on the wall of the gymnasium. It wasn't many years before then, we toured a 10,000 square foot building that housed one computer. It took up the whole building and wouldn't come anywhere close to the power that the cellphone I'm typing this on has.
So, I have had an 85$ Lincoln on my radar for about 2 months Gorgeous, beautifully toned cent. It has 0ne small carbon spot, by his temple. Are you saying this is a form of restoration?
Oh I think it would definitely change the appearance of your coin, for sure. Plus you could heat or vaporize your lunch
I would think this time of year must be getting his wood pile ready for the long cold Maine winters. Or maybe on his way to a warmer part of the country for the winter.
man if I had that at work,id be looking for rust just to remove. My adhd will be kept in line all day with a fun laser like tool!
Coins that have been ALTERED using lasers is OLD NEWS to the TPGS's. As a matter of fact, I've contacted a jewler in St.Pete, FL who uses a laser and when I get the chance I'm going over with some coins to see for myself what can be done and what cannot be done to the surface of a coin. Removing a spot from a coin is conservation IF THE REMOVAL IS UNDETECTABLE. It is considered an alteration (spot removal) if it is detected. In my experience, well-done surface alterations fool most dealers/collectors until someone (usually using a stereo microscope) catches them. Don't you guys get it. A counterfeit coin is genuine until it is detected. A cleaned coin is original until it is detected. This holds true for everything like rim files, mount removals, plugs, whizzing, cup & saucer alterations, etc.
Gotta admit a broad band laser is pretty cool, never seen one before. But then I thought it was pretty cool when I saw a 36 inch diameter cylinder of stainless steel sliced like bread with a high pressure jet of water in about 3 seconds. And that was 35 years ago. Of course getting rust off of metal like that in the video is almost as easily done (though admittedly not quite as fast) simply by using naval jelly - wipe it on and wipe it off. And that's been around for what - a hundred years ? But a broad band laser ? Yup, that's pretty cool in my eyes ! And yes, Insider is correct. Coin doctors have been using lasers to make light scratches, hairlines, and contact marks magically disappear on coins for years.
Clean coins? One word "don't." The only thing I'll put on my coins is acetone to remove PVC grime and all four TPGS allow acetone, because they can't tell if it's been used, it has no effect on the coin's metal only the grime. I was at the State Fair Saturday and a vender was selling jewelry cleaner and part of his pitch was that it also cleaned coins. How many people bought the cleaner and are going to use it on the coins left to them?
Now I don't know specifically what coin cleaner you are referring to, but all the TPGs allow coin cleaners (better known as coin dip) to be used just like they allow acetone to be used - because they can't tell if it's been used or not, just like they can't tell acetone has been used. In point of fact, 80% or more of all older coins in TPG slabs have had coin cleaner used on them. So every older coin you own, or that anybody else owns, that is in a TPG slab - the odds are 4 to 1 that that coin has been dipped.
