Crossing Guard Badge

Levy Court Crossing Guard New Castle County, Delaware. Stainless steel badge. It was a toss up between this and a bag of assorted enamel state pins, but Mr. Relic couldn't leave the badge there -- especially after bragging about our Delaware collection. Wondering if crossing guard badges come up often?

The number 24, is it the district?
