"I ordered Four, One Troy ounce specimens of Rhenium. My order was promptly acknowledged, and shipped two days later. The specimens were well packaged in individual airtight containers, and each ingot is well polished and serialized. I also placed more orders with RWMM for some other specimens, to diversify my holdings in precious metals. I realize there is some risk investing in these commodities, as there is no secondary market for these ingots I'm aware of at this time. "
