Can someone tell me what the bluish film that covers the coins that come out of proof sets and mint sets. It comes from the plastic that the coins are sealed in but I dont think its pvc. Does it effect the coins grade and how do you remove it without damaging the coins? Ive tried acetone dip but it doesnt remove it! Does anyone know...?
The haze is from the storing conditions. Some call it environmental damage, which is correct. All coins that aren't blast white, have ED, to some degree. There are many different kinds of environmental damage
Yes, if it's attractive toning and not haze it's a positive haze is a negative. MS70 can get some haze off
Please leave your coins alone for these reasons: 1. You've already hairlined one of them - fairly badly I'll guess. 2. Many people love the blue haze! So if you leave them alone you'll have more buyers. Those who like the toning and those who cannot wait to remove it. 3. There are chemicals that take it off in seconds. However, I'll bet your coins are not worth the price of professional conservation. If anyone does not know what they are doing they can ruin the coin even with proper chemicals. 4. Acetone does not always work on these without a good soak. 5. If you still wish to play around MS-70 and coin dips work when used (properly).
I know nothing about acetone.. Just know it smells weird when my wife takes her fingernail polish off
Try asking here before you just go and do something like that. Most of the time people will not want to dip it unless its been in the ground or has a lot of Crud on it..
The bluish haze is the beginning stages of toning. That's why acetone won't take it off. Yes, as already mentioned MS70 will remove it. But it must be used properly. And you do not want to use MS70 on copper because it will turn copper coins blue or purple. What you are talking about doing is the proper cleaning of coins. And yes it can be done without harming the coins. But just like it is with anything else you have to know what you are doing because it is all too easy to screw things up. So, you either need somebody to teach you, or you send the coins to somebody who already knows.
LOL ! I knew somebody was gonna say that one of these days Lessons are always free of charge ! However, and maybe unfortunately, or fortunately depending on how ya look at it, I do not give lessons on cleaning coins
Its really cool to be able to ask a question and get answers from people know what they are talking about. Thanks for the info GDJMSP..
I just realized... Every time we put change in our pocket at a store we're ruining some poor coin collector's day 100 years in to the future... From here on I am going to ask at the check out... "Here, do you mind putting my change in these cardboard holders? I have a stapler you can borrow."
That's Assuming we still have 100 years left on planet earth! With all the things going on in the world, things that i have been seeing, i find it hard to think we have 100 years left..
