I've found that various prescription pill bottles are almost made for certain coins. Other than the fact that they are free (if you or family and friends have them), they are better for storage than paper rolls. They are air tight and there is enough extra room in the bottles that you can slip a piece of paper or tissue between the coins to prevent contact marks. you can pack it with tissue to prevent movement of the bottle is too big. The bottle also provides protection from things banging in to it, unlike 2x2's. In my opinion, they are THE BEST, multi-storage container for lower value coins when the objective is to maintain the current condition. Yes, even better than the plastic containers made to perfectly fit specific coins.
