Storing PCGS Slabbed Coins

Make one of these:



As per this instructable:

The inline valve is the air intake (suction) up through the needle, the "free floating" vale is the output.

I put coin rolls/slabs/etc. inside a Ziploc. Close the ziploc realizing the more air inside when sealed, the more will need pumped out. Stick the needle in through the top plastic of the bag. Put a piece of tape over where the needle is in the bag. Weight down the needle's air hose so it won't move when you are pumping (this step not in the above instructable, but sure helps). Pump out the air. Slide the needle out while holding down on the tape.

My albums are stored this way as are most other things in my collection. Its inexpensive, fast, easy to use, and I have some things stored now for longer than a year that are still vacuum sealed.

I use el-cheapo brand bags since they work. Double zipper? Even better IMO. Once I did have some bags that did not keep the vacuum, so I tried others. I have not had that trouble again.

You could vacuum seal your entire plastic box. Thus quick access to everything.

I would think (not sure) the bag around the box would not fully "shrink" until the air in the box was also gone (?). Personally I have enough faith in this system that if I was going to store one of the boxes, I would drill an inconspicuous and small hole in it to make sure the air was being pumped out of the box.

The larger the handheld pump, the less pumping. The first time it seems a little slower than it should be, but that is b/c you are pulling air through a small diameter needle.

I find it only three or so pumps for a typical roll of coins in s bag. It depends on how much air I don;t seal in the bag before attaching the pump.

The link above includes parts list and where to get them, though they could be obtained locally.

If the slabs are not airtight, store them in polyethylene clip lock bags with small bags of silica gel, also in an open weave cotton bag.

If they are airtight, display them in a paged 12 pocket clear acrylic slab album.
Same approach if non air tightness doesn't bother you, and PCGS boxes then become perfectly OK.


Australian Proof coins are individually hermetically sealed in acrylic capsules, and you can handle them like any other low grade circulation coin.
Display / storage then becomes a matter of open personal preference.

No storage method on earth is technically air tight.

They're water resistant which are the only ones who can be submerged, which obviously means they're closer to being airtight than the others




If you really wanna go all out the intercept shield slips for the slabs

Baseball21, on the airtight comment, I was referencing PCGS' website.

I didn't find the slips after a quick search.

Dave, yes Ray has been a big help. I just need to sharpen the skills on slabbed coins.

It is amazing how I can image a cent from my pocket change and it looks like a thing of beauty.

I think I will stick with the blue PCGS boxes with my ziplock freezer bags and silica gel canisters. Take some good pics and forget about it.

He misspoke and it has been corrected including later in the article where they say virtually. It is the closest we have to an airtight holder for sure and I am a huge fan of it as it was a huge protection jump

Me too, and the clarity of the plastic is the best there is right now too
