The March of Dimes has been around for quite some time. I remember back when I was a young pre-teen; a radio station sponsored a 25 mile hike. I participated by getting folks to pay so much per mile for every mile I hiked and then the money went to the foundation. I did this for 2 years in a row and completed the entire 25 miles both times. It would begin in Cincinnati, Ohio and over to Covington, Kentucky. I had to cross the Ohio River on foot over the bridges that spanned the river, which was not an easy thing for me to do as bridges disturbed me. One in particular was actually swaying which made you unsteady on your feet! It was quite the adventure.

Thanks for posting this coin @ronavel, for it brought back a memory I hadn't thought about in years. Take care!
