A famous incident involving Miner's Delight occurred there in March 1893, which was widely covered in the press at the time in Cheyenne and throughout Wyoming, and came to be known as "the brass lock service mystery". Miner's Delight postmaster, James "Jimmy" Kime had attempted to ship eight registered letters via the Rawlins and Northwestern's line's Lander-to-Rawlins stagecoach to the Postmaster in Rawlins using the "brass lock service". The Post Office's so-called "brass lock service" utilized canvas pouches, which were locked with brass locks, with the only persons having a key being the Postmasters along the stage line. When Kime's pouch reached its destination in Rawlins some 120 miles to the southeast, however, the postmaster there discovered that someone had cut the pouch and stolen all the registered letters.
