Even the flips are only temp. The best cheap way is the type he has them in now "stapled cardboard.
Curious, why doesn't the ANA use the stapled cardboard? If the flips are temporary, then why does the ANA use them?
Plastic flips are available in various materials. "Soft" flips are made from polyvinyl chloride (PVC) which decomposes over time with disastrous results for coins. They are therefore not suitable for long term storage. Mylar and acetate flips do not contain PVC. However, they are hard (may scratch the coin if not inserted and removed carefully) and brittle. While not airtight, they are reasonable choices for moderate value coins that will be "left alone" for multiple years but less so for coins to be shipped or that will be removed and reinserted.
Mylar-line cardboard, often called "2x2s" but also available in other sizes, are similar to plastic flips. A coin is placed between the two halves, which are then stapled together (some brands contain an adhesive).
Tubes are plastic containers designed to hold a number of the same size coins. They are fine for bulk storage of circulated coins and can be used for higher grade coins, provided the coins do not move. A disadvantage is that the coins cannot be viewed without being removed from the tube.
Hard plastic holders are preferable for more valuable coins. They are not known to contain any materials that harm coins and offer good protection against scratches and other physical damage. They are available for individual and small sets of coins.
"Slabs" are sonically sealed hard plastic holders for individual coins. They offer good (though still not perfect) protection, but because of the expense of having a coin slabbed, they are generally suitable only for more valuable coins. Hope this helps.
