There are two types of shells: expanded and unexpanded. Expanded shells are stretched out slightly before they are hollowed out, so they will fit over any normal coin. Unexpanded shells are not stretched, so you have to use specially manufactured cut down coins to fit inside.
This is an un-expanded Half Dollar shell. Please correct me if I'm wrong, but I believe it's 40% silver.
