Vintage Cast Iron Still Penny Banks

Here are four cast iron still penny banks.
I like them because, for children of long ago, pennies were a lot of money that could be used to buy candy or a toy. Instead of spending their fortune on a treat, they were urged to save their money for a rainy day in a bank that was small enough and they could shake the bank to hear their savings grow.
All of these banks are approx. 6" long, all are made of cast iron. I'm not sure of their age, but, they do have some age to them. You can see where the paint was chipped and the cast iron base came through, they all have a patina that was formed on the exposed iron.
The first is a bull with attached horns. The second is, I believe George Washington in a Rev. War Uniform. The third is an Indian chief ( I recall seeing this bank in a Hubley catalog. The fourth is a rabbit bank.
