A quiet little country town, Dime Box (pop. 250) was originally called Brown’s Mill after the local gristmill that gave the settlement its start. The U.S. Post Office requested the name change because it thought “Brown’s Mill” would be confused with “Brownsville.” One resident suggested the name Dime Box because of the custom of leaving a dime in a box for the person who carried mail and packages from Giddings. Dime Box moved from its original mill site to be near the old highway, El Camino Real (now roughly Highway 21). When the railroad came through, the town picked up and moved again. The settlement left behind became Old Dime Box. The Dime Box Heritage Museum displays artifacts donated by local residents, including German and Czech quilts and a miniature Czech First Communion book.
