VERY FINE. AN ATTRACTIVE AND RARE COVER BEARING BOTH THE $2.00 AND $3.00 COLUMBIAN ISSUE.
The 2013 Ludeman Columbian Dollar-Value Cover Census lists two covers with this combination of the $2.00 and $3.00 (apart from covers with additional dollar-value stamps).
The town of Cato (or Kato) near Bellefonte, Pennsylvania, prospered when the Kato Coal Company began mining operations in 1890. S. M. Buck was the postmaster in 1892 and 1893. The mine was eventually depleted and the town lost almost all of its population by the 1940's.
