The more they build here, you get pools, golfcourses, manmade lakes and ponds etc etc. The avg humidity has increased since I first came here. I would not own Lincolns if I lived in FL or GA. The Travers book ( I think it's the Travers book ) says dont even bring them for shows..........

 

Makes sense create a vacuum. Less air is less sulfides and humidity. I'm more curious about whats in that ANACS Slabb. Looks like an 1882 IHC variety of some type.

 

Haaa, Harry, I posted that on another forum and the same question was asked! Indian hunters sure noticed! It is a 1882, Snow-6, ANACs VF35. I brought it from the bank to try and polish the plastic so I could get a good photo of the misplaced dates which as you probably know are quite difficult to see through fine scratches. It was on the desk, so I just used it

Was somewhat difficult to find.

Nice one Jim. You made me get my IHC guidebook out. The Snow-6 is rare and the most elusive of the 1882 varieties. Very Nice! Maybe for New Years Day you can post the coin. I can live with the scratches on the slabb.

 

Cold Hard Cash?

 

48 HRS results.

The 48 hrs test period came to an end. After removing carefully from under the water, I noticed that the plastic was still tight against the paper towel and I could see no water or condensation inside. The towel appeared completely dry.

Now came my error in procedure. I carefully tried to wipe and blot any water near the outer zip-lip. Then I opened the zipper ( my mistake) as the vacuum drew some water into the bag ( sucking sound). The edge of the toweling closest to the opening show a thin line of moisture. The pocket change was dry to toweling.

If I really wanted to continue testing, I would try to loosen the valve to relieve the vacuum before unzipping but I need the room for cooking now.

My thoughts were, that if it can hold a vacuum it can keep out most if not all the moisture. I'm convinced that this would be an inexpensive way to preserve coins in slabs. And raw coins too.

After I noticed 2 slabs that seemed to have moisture in them I needed a better way to protect them. I had left them sitting out for longer than I expected. When I slightly squeeze the slab there's a spot of moisture that flattens out. If I put these 2 slabs in the zip-lock and add desiccant then vacuum it, I think I might get the moisture to travel to the desiccant pack. I hope.

Now, to buy the Ziplock vacuum unit.

Jim,
Are you convinced enough to give it a try with your coins?

Bruce

 

I don't see where they could do any downside. The bags are more costly than the non vacuum type of ziplocks, but not much. If a person is inclined to use regular bags, this would be a definite improvement. Since many say modern slabs are closer to being airtight, I would probably extract additional air over a several day period to allow diffusion of air in the slab to evacuate it before storing it. I suspect these bags have a better zipper than the regular bags

It isn't foolproof, but it is an additional barrier. I would have no hesitation in using it,
but mileage may vary.

go JIM yeah !!!!

 

Well when you were a teenager the ziploc zipper was made of twigs and the bag was made of leaves. :whistle:
I am just kidding lol. The condensation got to it. :smile

 

Doug, I'll have to check when I get a look at them again. I hope they're PCGS and it's oil.

I still think the vacuum bags can't hurt and with a silica desiccant in them there's all that extra protection.

Jim, just a thought, but these bags of course are for food storage, and I don't know of anybody who stores food for years, let alone decades. Try that water test in 20 years from now and let us all know then how that seal holds up.

 

I don't know Eddie , Ive kept some wheaties in the regular non zip bags with no ill effect for over 30 years , I think these will be fine for a few years extra protection , of course I'll start with some cheap proof sets that aren't getting any protection to see how they work .

That's good to know because I use zip lock bags for my wheaties, too, Rusty. Are you a coffee drinker? I keep those bags in plastic Folgers buckets; they stack up real nice. Just label them with a black marker, 50s, 40s, whatever. I keep my quarters, dimes and nickels in zip lock bags in Maxwell House buckets (they're blue and the Folgers buckets are red). Which reminds me, I need to drink Maxwell House, next, because I need another blue bucket.

 

Quit drinking coffee and switched to green tea when I heard of it's anti cancer properties , still gives that caffeine kick too , but tastes like cr-- .

Green tea? Affects my collecting abilities. Got to stick with the coffee....

 

Today I did go to the store and picked up another pump and some larger size bags. mainly for use with food today. Surprisingly, they aren't in all stores that carry regular ziplock bags. Using them, it did dawn on me that this could be an easy way to try ATing coins in slabs if one was so inclined, but probably best not to discuss that.

I could readily see someone making the bags a little more "coinish", maybe with outlines of state quarters or bust dollars and selling them on coin supply sites for good prices.

If you put coins in the quart size and sealed with dessicant, and then put 2 or 3 of those in a gallon bag with a color change dessicant and vacuum that, you have a 2 stage protection system. If the outer bag fails, the dessicant would start to change, open the gallon bag and move the still sealed inner ones to a new gallon bag.:rolling:
