A vintage coin bank can be purchased at online marketplaces such as eBay and Etsy for as low as $10 or as high as $750, as of March 2015. Another option is to search for vintage coin banks at specialized vintage and antique marketplaces such as RubyLane.com.
Before the purchase, determine the actual value of the coin bank. Buyers should examine the coin bank for cracks or chips and gather as much information as possible about the manufacturer online or at a local library. Special care should be taken with antique cast-iron banks sold under the vintage category, as some of them are reproductions.
