Coin Protection is a tricky topic. You shouldnt ever give up on a coin - remember, the plan should be that the coin should outlive you by a couple of millenia.
The key points are these: Removing anything from the coin which could harm it and then making sure nothing gets to the coin that could harm it.
Methods: First, all coins should be deionised to remove Chlorine which causes BD. any chlorine ion will destroy the coin given time. Removing the ions involves deionised or distilled water - soak for about 12 hours at a time and then replace the water, removing any green specs without remorse, straight down and into the metal.
Second, remove surface impurities like olive oil which could cause discolouring and eventual corrosion. Also with DW or Acetone - I've found it useful to burn off anythign that refuses to emulsify, but you'd need to repeat the DW treatment to ensure biproducts dont cause issues.
Then, seal the coin in wax. Before hand, remove the water by heating it in an oven for a period of time. Wax it. This gives a layer of protection against airborn woes. Buy Ren wax - its pricey, but it lasts forever and its really good at what it does.
After that, storing the coin is important. the wax will protect it, but PVC would eventually get to the fabric of the coin. You need something like a Saflip. HEat sealed would be even better to exclude gases.

Yes, they seem to be the right thing.
Another point is, you should watch out for something called Bronze Disease. You will come across it eventually, it is a bright green powdery substance on the coin. If you can pick it off easily with a pin, it should be treated (more of that later). The important thing is that if you find it, don't store the coin in a flip until it has been stablized. If you find a coin in a flip with BD, you should throw the flip away.

Ben, never heard of the Acetone treatment, but I do have some in storage. But I did read something about Red Devil Lye and that stuff scares me.
I will research Ren Wax. When waxing, the wax should be clear so you can actually see and enjoy your coin.
Thanks for all the info. All of this is new to me as I have researched about coin collecting for the past two weeks (my wife going to kill me, because it takes away from our business, LOL) but some of the ideas that are presented here I have not seen, heard or read about. But I consider the people on this site to have the knowledge and know how.

Don't try and take too much on board all at once. Ben gets very technical, but he knows what he is talking about. Start cleaning the coins first, then you can post questions as and when you need to. Rennaissance wax is used on bronze coins only, not silver. The British Museum uses it to preserve their artifacts, you can't get better recommendation than that. Your ebay seller has it: http://www.ebay.com/itm/Renaissance...em4cede56589There is no rush to get it yet. And there is certainly no point in wasting in on a blasted coin.

Yeah, you wont need to use it until you have quite a few coins cleaned. Its much more important you learn the cleaning process properly first. Patience is your friend in this pursuit.

long story short philip, if you're not cleaning or anything just make sure you have non-pvc flips..the one you posted above would be just fine. just note that they don't come with paper inserts to write you coin info, so if you want to do that you'd have to make your own (i always by flips that come with inserts).

If you buy a quality coin, there are several ways to store it, but do not use wax. At a major coin show almost no coins will have been treated with wax. If you are worried about corrosion damaging your coin further or "bronze disease", you are acquiring low-end coins. Then take the advice of those who collect and know about low-end coins. But leave quality coins alone. You may touch them, but keep them away from things that can scratch them, keep them away from damp, and if you use flips (I do) be sure they do not have PVC, that is, be sure they are "safe". Unfortunately, safe flips are often brittle. They are not soft (the soft flips have dangerous PVC--avoid them) and their edges can be sharp enough to scratch a pristine coin, so be careful sliding the coin in and out.

All of the information above should be helpful. When I store them in a safe or a locked area I also put the collection in, Zip-Lock bags. This idea came from a number of CCF members.

My preferred choice for coin protection is by Smith & Wesson... Oh wait, you were asking about coin storage. :)
The safest method of coin storage I have seen are those little sewn felt pouches placed inside acid-free paper envelopes. I don't know were to get the pouches, but the acid-free paper envelopes are easy to find via Google. The second safest is the "non"-PVC flip (however they do have a small amount of plasticizer, so they aren't completely PVC-free). If you want to go high-end, you could get yourself an Abafil coin case (www.coin.com) and store your coins in it... All storage types have some drawbacks (for instance, the coins slide around a little in an Abafil case, over time causing wear; the non-PVC flips can scratch coins and are brittle; etc.)

I don't consider myself 'ancient' but in my younger days I had the pleasure of meeting some rather ancient fellows (Haaarvard Class of '25 and all that) and they all exclusively used the acid free paper envelopes. Now that might be because that really was the only option away back when. But sometimes the simplest solution is the best. I use paper.
