Bags are basically 100 rolls and a box is half a bag. Dollars are a bit of an odd item though. With the old
Ike dollars and older coins a bag was $1000 and a roll was $20. (They didn't have boxes at the time.) When the
SBA came out a bag was $2000 and a roll was $25 and a box was ten rolls. (There may be other box sizes as well, I don't know.)
