This is a fairly new collection for me thanks to my Round Top trip earlier this year. I am not sure how quickly this collection will grow as I don't see money savers often at estate sales. My eyes are open for them now tho. Most of them were distributed by banks or savings and loans to encourage saving with children.
It started with Dime Kitty. Dated 1954.
Still a small collection, but a fun and unique one. If you have an idea for a future collection challenge, leave me a comment and finish the sentence "Show me your collection of ____." You just never know what collection will show up each week.
