Vintage selling Thunder Basin Coal Co. Solid Brass Belt Buckle

This solid brass belt buckle represents 750,000,000 tons of coal from selling December 1977 to November 2002 from the Black Thunder Mine, Thunder Basin Coal Company, Arch Coal Inc. It is in excellent condition, and I do not believe it has ever been worn. On the back it says Midwest Trophy Mfg. Inc. (MTM). On the front is a coal operation digging the coal and a crane loading it onto a big truck. It is a great piece of memorabilia of the great coal days. Good looking buckle that measures 4" wide by 3" tall. In new condition.
