Commonwealth Bank money boxes have been a staple of the bank since 1922. The tin on the right was modelled on Commonwealth Bank's former head office in Pitt Stress. The tin on the left was a model of the bank's former building at 48 Martin Place.
The 'pink palace' money box, left, was issued after the 1931 takeover of the Government Savings Bank of NSW.
Next year we'll be celebrating 100-years since the money box was first released (for a sixpence at the time). When the bank issues a commemorative money box next year to celebrate the occasion you can reference this post as the source of their inspiration.
