What is a 425 grams ballistic roll?

Sounds like something from the World Monetary Reserve, a private outfit that packs ordinary circulation coins in special holders they call "ballistic rolls" and sells them at significant markups.

However most of what I've heard tells me that "ballistic" actually describes how people go when they find out that they've paid 3 or 4 times as much for these coins as compared to just getting them from a local bank.
