Basically what
Conder101 said. This has been noted in posts in the past about those rolls. And it is not just pennies, some have had the same problem with other denominations. Not sure if all are like the one I had but many in the past had a slip on type cover and it was that type for me that sort of got that way. Most of the more recent varieties all have screw on lids and never heard of anyone having a problem with those. Try the hot water system. Should be the safest method.
The above is based on if your discussing the hard plastic type of rolls. Others here have already thought you were mentioning the sort of soft, saran rap type.
