just wondering. do any of you "zap" your holders (air-tites,kointains,2x2 mylars) before housing a coin?

any fears of moisture entering from the canned air? thanks.image

    As long as you hold the can upright, there's little risk of moisture entering. But, one tilt of that can, and whatever that liquid is goes all over creation. I fried a keyboard last week that way!

    the other problem is that the air may cool the surface enough (if you do more than just a quick blast) to cause condensation from the rapid cooling. might be best to 'zap' the item and then set it aside for a few to allow it to warm up to room temperature again.

    Go to the baby section in the drug store and buy one of those aspirators. (Bulbs with a little tube). A few quick squeezes and all dust is blown off. No moisture, no chemicals, just air.

    just blasted a unc large cent real good yesterday no problem. Done many coins never a problem. But info already posted regarding tilting can is accurate, don't do it.

    a quick burst seems to be okay...can held upright, of course.

    The cans of Dust-Off and other compressed air have chemicals added to discourage the practice of "huffing" (spraying the contents into a bag and inhaling it to get high.) Those chemicals may potentially damage surfaces of coins. I know that you don't get allot of force from the aspirator, but its clean and no chemicals. Quick, hard squeezes will get you some nice short bursts of air. But, hey, if you want to use compressed air, and don't mind risking your coins, get the dust-off.

    I've got one of those and trying to blow something off of a coin is not as easy as it sounds. Perhaps its just me but when I squeeze the bulb, the tip moves which makes aiming them a little tricky. Getting it close enough to direct the air is also fairly tricky as well.

    Of course, thats just me and I continue to use it because I know that any type of compressed air uses either sometype of propellant which can damage or some type of lubricant which can also contaminate your coins.

    Possible. Come to think about it, compressed air emits moisture.

    Next time you put air in your tires, shoot some air onto the palm of your hand. You can feel the moisture.

    As coins are in the process of being sealed, an employee sprays compressed air on them to make sure they are free of dust & debris.

    This moisture COULD be responsible for spotting PCGs coins - mostly American Silver Eagles.

    Food for thought.

    Always be careful using canned hair. Short, hard bursts are bests. Do not use long blasts, as that is more likely to make it spit. Hold the can upright. If it starts getting cold, let it sit for a bit. If it's a new can, aim a long shot away from anything because sometimes they will spit the first time you try to use it. Also, when the can is getting low of air, don't use it anymore. Save it for other uses, but don't use it where you're going to be putting a coin or on a coin.

    What to TPG'ers use??

    I don't know if they use anything, but there's a lot of junk on some of these coins, they have to be blowing if off somehow.

    Don't ya think ?

    Anyone use a hair dryer on the warm or cool setting? I would think that it should work.

    Boom, I've had milk spotting on non-PCGS or any TPG slabbed coins.

    I used a shop vacuum before on both coins and holders. It worked really well, but it would be easy to accidently fumble and suck the coin into the vacuum. I held tthe coins in a vinyl gloved hand and didn't have a problem though.

    I use it to hit albums before putting coins in, but not the coins themselves...

    Use whatever!
    Canned air or compressed air will not make a lick of difference, just don't spit on the coin.

    The conclusion one can arrive at from the various answers is that there is a lot of compressed air in our hobby. Respectfully, John Curlis
