The Cavilier Attitude towards flip

I've noticed that a great deal of coins are sold in those soft plastic flips. To my knowledge, those are not Mylar and will cause damage to your coins over time, and I'm not talking about toning, but Verdes and corrosion.

This is a big problem and a lot of coins are going to go down in the next 30 years because of this. Additionally, I'm just not certain of the plastic capsules so many new proof some it. They can also be trouble, but I'm not sure.

Hmmm, pretty much any coin I buy goes into a "Saflip," and what it came in goes in the trash (speaking of flips only, that is.) I can't stand the thought of saving 10 cents leaving a coin in those soft flips I think you are referring to.

 

I put all the coins in Mylar flips, the stiff ones. The problem is I lose a lot of documentation when I need to transfer with the coins, such as variety types etc.

 

The plasticized flips are popular with dealers since they won't crack after being opened over and over again. I can totally see why dealers prefer to have their inventory in them. Collectors just need to be cognizant of long term storage, and not keep them in the packaging they came in.

This is what I do. Once I am satisfied with the coin, I throw away the plastic flip and transfer all information to a saflip, keeping the dealers 2x2 insert.

 

Doing a little experiment myself, I've found that the green pvc film develops and is noticeable after 9-12 months of storage in those flips. At that stage, the coins can be dipped into acetone to safely remove the pvc film. Wait any longer than that, and the best that you can do to conserve is to send it to NCS. Even then there's no guarantee that will solve the problem. And any copper coins is going to be tougher to treat, pvc reacts quicker to that base metal.

If it smells like a new shower curtain, then it's garbage

 

Frankly, I don't like the stiff ones either. There's too much chance of scratching/rubbing with repeated handling . I transfer the coin to either a 2x2 or a plastic coin holder.

 

Yeah, but you like "nice" coins rather than the dirty old dreck I care for.

 

Dealers often have inventory for years.

 

Not all "PVC" flips are the same. It is the amount of the plasticizers that count. Companies have reduced the types and amounts of plasticizers in the last decade, and even this amount usually leaves the plastic is a fairly short time. If you want flexible, you need plasticizers within the PVC, if you want to remove PVC, you get stiffness in the material, whether with PVC or mylar.

You need to train your dog to sniff PVC plasticizers

 

The longer the time after manufacture, the less plasticizers in the flip.

 

I'm afraid I don't follow you. If you use SaFlips, you can get them with the small inserts to write info on and put it in the other pocket. Another option would be to use a label maker (I use the P-Touch). So, how do you lose the documentation?

yah - your right

 

Yeah, I love buying coins in flips since I can be lazy and just take the sellers paper 2x2. I hate it when they are in cardboard, since one I have to get them out without scratching, and two, copy over everything since I only keep my coins in flips.

I love to hold them. Is that weird?

 

Hey Chris. Well Hello Chris. Where having a Chris Convention ...
Great Chris.

 

I don't know how long some of these coins remain in the PVC holders. But at times I have seen some cloudy looking holders. The dealers I buy from use the 2x2 cardboard flips and airtite holders.

 

Not to mention unexpectedly splitting open allowing the coin to fall to the floor. Has happened to me many a time.

 

I'm not sure why any coin dealer would use a flip with any amount of PVC in it, but many, many do. It cost literally less than a cent more to upgrade to an archival material flip. If it's that big of a burden, I wouldn't mind paying the extra cent rather than worrying about how long a coin has sat in a dealer's case in a PVC flip.

I guess it depends on your collection. Coins struck in pure nickel, for example, can be put in almost any flip... Only coins containing copper tend to be aggressively affected by PVC. Ultimately, it is controlling the humidity of where you store your collection, that should matter most.
