Hi,

Some airtites holding my coins had smudges from something, and won't come off. I decided to get new airtites for them. Any tips and advices on how to change these coins into new airtites without harming, marking, or scratching the coins? These coins are BU silver btw. Please help me out. Thanks.

Well,just use common sense. Be extra careful and mind what you are doing at all times.

I can't remember a recent thread talked about a product to remove scratches and defects from slabs, may be cheaper than replacements.

It seems to me that the smudges perhaps have either one, or maybe from these two causes
1. abrasive scratching
2. exposure to an organic solvent.
Both are injurious to acrylic products, and so that cause ( or causees), needs to be found and eliminated.

You are right to consider replacing the airtights affected.

Press snap close acrylic airtight capsules, with reasonable care can be prized open, to release the coin. Re use of the airtight capsule after 3 or 4 times, will weaken the seal.

Press snap close acrylic capsules are OK, but
I prefer ex British Royal Mint screw airtight capsules, which offer a more secure gas seal, as well a much more positive mechanical seal. They come in sizes related to the coin they originally protected.

My LCS regularly releases the original proof coins contained therein, and saves the capsules for re sale, at 50 Cents each.


For proof coin sets, it is common practice to house all coins in a single case. If the case is fogged or smudged, great care and patience is needed to remove such blemishes.
Ideally, the coins should be removed if possible, and the blemishes removed with a superfine cutting compound. This cutting compound can prove disastrous to proof coins, and that is why they should be removed. The cleaned acrylic case needs to absolutely perfectly clean, before the coins are placed back in the case.

Unfortunately some cases containing proof coins cannot be opened, because they are ultra sonically weld sealed, and so the case has to be polished with an ultra fine cutting compound, with the coins remaining in the case. Very difficult to hide your corrective polishing work.

Here are couple videos. I didn't watch them completely, so not sure how good the advice is.

Don't do the top video... He actually hit the coin with the dental tool, and is not wearing gloves...
I found a sharp small pen knife works best.

Capsules are cheap to replace, but there is the risk of damage. If you want to try polishing the capsule to remove scuffs and scratches, you could try Plastx or Novus -- those are more expensive than capsules for sure but you only need a small dollop so you'll have a lot left over for other uses. I used Plastx to clean up some PCGS slabs and was quite impressed with the results: not perfect, and good only for light abrasions, not deep scratches.

If the scratches are too deep or you have only a couple of things needing attention, replacing the capsules may be the way to go. Just be careful that you don't damage the coin (or yourself) in the process.
Working on: Peace dollars (two to go), US type (Bust era), Chinese pandas, and San Francisco tokens.
