Piggy bank is the traditional name of a coin container normally used by children. The piggy bank is known to collectors as a "still bank" as opposed to the "mechanical banks" popular in the early 20th century. These items are also often used by companies for promotional purposes. The use of the name 'piggy bank' gave rise to its widely recognized 'pig' shape, and many financial service companies use piggy banks as logos for their savings products.
