Coin Storage

I have a few Whitman Albums that I have coins in. I havent had any problems with them, but I havent been collecting nearly as long as Carl though.

I think most paper bank rolls contain sulfur. I believe this is one of the reasons many coins have brown edges.

You may want to purchase some coin tubes- they serve the same purpose as a paper roll but they are made of clear-opaque plastic and they usually have screw-on caps. You can purchase them for any denomination and they are much safer than medicine bottles.

As already noted the main difference between a Folder and an Album is a folder does just that, folds. You can see only one side of the coins due to they are placed in slots with a paper backing. In an Album you open it as with any Album such as for photographs or even a book and turn pages one by one or like me flip through them.
Way, way back folders were all there was and that is where I used to put all my coins until Albums started to be manufactured. That was back before even the Red Book. Later in life as I removed coins from a Folder and placed in an Album I noticed dark lines or dots or even entire areas of the coins reverses toned, corroded or heavily tarnished. As I studied manufacturing methods I found the Folders were being made by a full sheet of paper, dyed blue and completely covered with glue. Then slotted cardboard type pages were layed on that paper. No attempt was or could be made to remove the glue from inside the slots so there is stayed until my coins made contact with that stuff. As a kid it proved advantageous since most of the coins I had were worn excessively and would just fall out of the folders. As any kid can tell you the thing to do was to spit on the reverse of the coin and put it back into that slot. The spit worked well with the glue and the coin stayed in place.
Obviously a Folder is not intended for a true coin collection but are really great for people that just want to do something with coins.
