Is there anything you can do to "clean" up this hazy or junk that is on the face of this gold coin without damaging it? Ammonia maybe? Thoughts please.
I understand that. What is MS70 and where can I find it.....unless you were guaranteeing me that is what the grade would be!
Joe, check out JP's Corner. They have the MS70 product you're looking for. I have some but haven't used it yet. I'll get around to dipping som old common silver first. Let me know how it works on gold, as my 2006 Proof Buffalo developed a red spot on each side. :crying: http://www.jpscorner.com/Cleaning_Supplies.htm Bruce
Be carefull. My suggestion is if you really want to try to get that haze off, start with the simplist possible and least distructive methods. By that I mean distilled water. And what most always forget is how to handle those coins to be dipped. If at all possible, do not use metal tongs, tweezers, forcepts, etc. Way to many have scratched coins doing that. Using plastic gloves is a decent idea and by the edges only. Now if that doesn't work, and it really shouldn't, try the old standby Acetone. Look up the many, many stories on this web site about Acetone. Again, the method of handling is rather important and don't use plastic gloves here. Now there is a really good chance the Acetone will also not work. So here is one more and rather stupid idea. I had a 1995 Lincoln Cent Double Die in about MS-65, which I purchased for almost nothing due to a finger print. With little to loose, I dipped it in jewlery cleaner from Walmart. Finger print vanished and nothing else happened to that coin. Similar I had a Proof Dime with a finger print and tried the same thing. Also, worked and to this day, no ill effects. Naturally both were rinsed in distilled water after. The bad news is now Walmart has changed whatever it was. They now carry several different types and none look like the one I used.
Water and acetone will not work Carl. A coin dip (jewelry cleaner) will work. But it will also remove a minute amount of metal from the coin just like any coin dip does. MS70 will not. To remove haze from Proofs, except copper (big no-no on copper), MS70 is the preferred product.
An endorsement by GD is good in my book! :thumb: Im not going to rush into this. I will take my time and do it right. I definitely don't want to damage the coin in any way. I really do appreciate everyones comments and help.
Hmm, I learned in my class I took at the ANA on conservation that you can use 2 things) 1) Do what I did before and scratch it off with a knife (This wasn't taught in the class, but oddly enough Brian told me he's seen coins submitted to them with copper spots scratched off too...people would take a razor blade to them. Don't actually do this) 2) Take a blowtorch to the copper spot, it should melt right off (Some people did this apparently, again don't do it) 3) Use jewel luster. Use a tooth pick (be very careful) on gold coin to the copper spot, dip the toothpick in jewel luster, put a very small amount on the toothpick, dab gently on copper spot. I'm going to go through my notes here for you... Use Nitrile gloves. Put a mat or something underneath it so if you drop it it catches. Don't breath on the coin...remember to neutralize the coin in water after the dip
I understand that PCGS or NGC will rstore the coin for you,at a price, then encapsulate it. To me, you have to weigh the coin's value againt the cost . Try these other methods on some culls if you have them. Even Tarn_X will work .What else it does is not known to me. I have worked in the plating industries before using caustic soda to cyanide to trichrome. I have seen acetone that would take the flesh off ya. So do not go beyond the hardware store for that . Ororder some stuff these guys say work.Many options hard to do with out losing value .
Don't misunderstand Joe, I do not endorse using MS70 in any way. In fact, I will always advise that it not be used. But you wanted to know what would work so I told you.
