As many of you know, Cinco de Mayo marks the victory of a rag-tag bunch of Mexicans over the most formidable army in the world. The Frogs hadn't lost a battle in a half century.
However, the Mexican victory on Cinco de Mayo of 1862 was short lived and Benito Juárez set up a resistance movement in northern Mexico. At a cost of $57.00 per rifle (including 500 rounds per weapon), paid for in silver coin, Juarez purchased 1,000 Winchester Model 1866 carbines in .44 caliber. The rifles were stamped *R.M.*, for *Republic of Mexico* and marked with a sunburst. Today, these rifles are worth upwards of $8,000.00. About ten times their 1866 value after adjusting for inflation.
