Dime bag,
A bag to hold a small quantity of loose items. This term, and the related one nickle bag, both most likely are linked to stores that called themselves Five and Dime Stores. Woolworth's the chain that founded this concept, used to sell items frequently for a nickle or a dime and most stores had a
candy counter. The
candy counter was stocked with
candy in bulk bins and it was purchased in small bags and customers either requested a nickle bag or a dime bag.
