Hi lol,
Everything that areich told you is correct. Even the PVC-free (Mylar, etc.) plastic
flips are not perfect. But that's what I use. Why?
There are 3 reasons:
1) That's what I started using from the very beginning of my collecting. And I don't feel like switching over to trays or cases or whatever at this point.
2) I like to keep as much information as possible with my coins. I find that Mylar plastic
flips are best for this. I write the information on home-made paper tags and insert them into the opposing pocket of the
flip. Doing that isn't as easy with trays or cases, and the tags can get lost.
3) My
collection is too large. Trays or cases take up much more space than plastic
flips. If you only have a few coins, then yes, trays or cases may be practical. But once you get beyond a few hundred coins, trays or cases, in my opinion, are not practical. They would literally take up so much space that it would be ridiculous. My own ancient coin
collection consists of approximately 2,000 coins, possibly more. If I stored all 2,000 of my coins in trays or cases (instead of in Mylar
flips), I'd probably have to rent out a storage unit just to store my coin
collection. Or half of an entire bank vault.
By using Mylar
flips, my
collection is in a more compressed state. It is more efficient use of space.
Of course, I know that areich will disagree with me.
