I was approched by a potential customer who wants to plate 24k gold on his Gold US Sacagawea Dollar. He wants them as gifts for his golfing buddies to use as ball markers on the green. Seems the original finish tarnishes too easily/quickly. The Dollar is a Manganese/Brass alloy (88.5% Cu, 6% Zn, 3.5% Mn & 2% Ni). Any thoughts on how this might be accomplished?
