Do you remember these? School children in the 1940s and 1950s filled them with dimes and thus contributed to one of the biggest changes in the history of medical philanthropy. Millions of donors gave small donations instead of only a few donors giving large gifts. Giving to medical causes changed forever, and school children knew they had a part in helping to rid the world of polio. Today the March of Dimes continues to collect small donations from millions of donors as part of their fundraising efforts to help babies born prematurely.
