Does anyone use these? One of the sellers I buy coins from on ebay uses these whenever I order something. I find them quite less annoying and a bit more study than 2x2 cardboard holders, also no need to deal with staplers. I am wondering though if there are any books or pages for coins anywhere that you could use these with? |

Be very careful, many of these "flips" contain PVC and can permanently damage your coins.

In the UK, the flips are much more commonly used than 2x2's. Yes, some are vinyl but there are mylar ones. I keep some of my lower value coins in them inside old Kodak slide boxes and have some that have been stored like that for 20 years with no sign of damage. They will also fit in the 20-pocket album pages that also take 2x2s.

Can't be all that bad.
I would never use them for bronze or silver proof coins, on a permanent basis.
but OK for gold and less valuable coins World coins in less than uncirculated condition.
I have regularly seen them used by auction houses, even for ancient gold.
My avatar coin was shipped from the UK in a PVC flip,
but I put it in a 2x2 with thin, hard PET plastic sheet inserts cut from a food packaging box, for extra protection.
I have been slowly building an OFEC collection of 19th Century World coins (1800 to 1900), over the last four decades. Most are heavily patinated anyway. The majority of them are in 2x2's, but some are in soft plastic flips. The sort of collection my grandfather would have built, had he been interested. Krause Catalog helps.

Nice for shipping coins in but use the cardboard style for longer storage times.

Agree, 2X2s are the best.

I use mylar 2x2-sized flips for my ancient and mediaeval coins, because 2x2s tend to both be awkward for their odd shapes and they obscure details on such coins. I buy them in bulk from an ancients supplies store. I also use them for well-worn modern coins, for the same obscured-details reason.
Re: PVC: if a flip is soft and flexible, then it's likely plasticized PVC and therefore "bad for coins". If it's rigid, it's almost certainly not PVC and probably "safe for coins".
I definitely would not recommend a flip for anything that still has original mint lustre on it. A flip by itself does very little to prevent oxidation and tarnish.

I use these no staplers and pvcfree both in 2x2 but this is the bigger size. Only to slip the coin in And best of all no staples  |

In relation to Sap's last comment,
PVC free album pages can at least help in a minor way to slow down oxidation and tarnish, but they are not a guarantee in this regard.
Pre glued 2x2's OK, but the very thin Mylar membrane can still be somewhat porous to water vapor and oxygen, especially in a humid climate. In this regard, I am equally happy with both stapled and pre glued.

I gave up using the self stick cardboard ones 20 years ago as the blasted things have a habit of partly opening and then the coin falls into the gap to be stuck to the glue. I won't use the stapled ones as the risk of the staple scratching other coins is not something I'll risk. I use 2X2 Saflips with an acid free card in one side to record details. I've purchased coins sometimes from dealers where they have heat sealed the open ends of the flips to stop the coins getting exposed. So I presume that it isn't hard to seal them.
And for crown sized coins I have 2.5X2.5 Saflips that store perfectly in old PCGS boxes while for the 2X2 I use plasticizer free sheets in plasticizer free albums and then store them all in commercial safes (that I purchased cheaply from when government departments move).
Also for moisture you can put containers of moisture absorbers in your safes.

I won't use plastic flips for any reason - I'm concerned that the coin can get scratched plus they are not sealed from the environment. getting them out can be a hassle too if you needed to get removed. When I was sending my ASE coins to PCGS, I placed the m in the flip like they request, and I got low grades in return. so I then bought larger flips and when putting the ASE in it with the OGP capsule, I got 69 and 70 graded coins back. Coincidence? Maybe  |
