These coins were collected from the Plowboy site in Shawnee County and donated to the Kansas Historical Society in 2017. The Plowboy site was home to the Kansa, the Potawatomi, and Euro-Americans. At various times, the site contained a farm, a trading post, and a post office with nearby military trails, Mormon routes, a railroad and the California-Oregon trail. On the top row is a shield nickel minted in 1873 and a wheat penny minted in 1916. On the bottom row are two half-dimes with a seated Liberty with stars and arrows, both minted in 1853, and a mercury dime minted in 1918.
