I have a bunch of proof and uncirculated modern coins that I'm going to transfer to air tight capsuls. I absolutely want to reduce the possibility of contamination as much as possible, so I purchased disposable white cotton gloves and disposable face masks. For my first one, I put an uncirculated Sacagawea in and pressed it tight. When looking over the coin I noticed a piece of dust inside the capsul. So, what do y'all do to prevent dust from getting inside the capsuls?

Compressed air. Same stuff you use to blast gunk out of your keyboard. I have pugs. If I didnt use it, everything would have a pug hair in it!

Sweet link, John1! Can't beat the price AND free shipping. I just picked one up as I am going to transfer my ASEs from OGP capsules into Air-Tites here shortly...and I have a dachshund.  @smokeriderdon, I would worry about holding the canned air at a weird angle and spraying liquid on my coin or at the very least freezing the moisture out of the air. |

At $1.32 delivered from Hong Kong, how do they make money after postage, ebay and Paypal fees? |

I have no idea with some of that stuff. I import stuff all the time from China for my ebay buisness. When I sell used cameras I almost always have to replace the lens caps and I can get them for like .42 free shipping. It takes a month to get to me but I have no idea how they could make money at all. |

All coins should be rinsed with acetone before they're put in, I do this for ALL my coins. Before the rinse, I blow-out both parts of the Airtite with canned air so there is no dust. Then rinse and right into the airtite seconds later.

BadThad, would you please explain why coins should be rinsed in acetone? Does it not leave a residue?

It seems as if your gloves are not lint free, or they electrostatically attract dust. Better to use fresh food handling gloves. For air tight capsules, I use ex British Royal Mint acryllic screw type. With a bit of luck you can also find the snap shut leatherette covered steel box that the capsule came in. I am usually able to get both from my local coin dealer. Capsule $0.50, the box $1.00. Coin doesn't match the lettereing on the box, but I don't care. |

How exactly do you "rinse a coin with acetone"?
Thanks for any pointers as I have never done it.

A high quality acetone should leave no residue! It evaporates instantly. Lincoln Cent Lover!VERDI-CARE™ INVENTOR https://verdi.care/

Thanks for the suggestion on using a glass pipette for the rinse. Are you also wearing gloves and do this outside for ventilation to avoid issues with the effects of acetone?
I appreciate your help, I am in the process of moving my cent collection from an inexpensive Harris folder to a Caps Album.

I was always under the impression that the asian sellers sell for so cheap because of operating costs and bulk shipping discount. If they sell 1 million widgets at .02 profit, it starts to add up.
