Compared to other Aurum, I like how Metal Mark Standard is presented and packaged. Their artwork and trade-dress also set them apart from their peers. Using the subscription program, they are the lowest cost Aurum yet, but offer a premium customer experience. (Liquidity at this time is likely similar to other non-Goldback Aurum. ) Service from order to receipt is quick, efficient, and well-communicated. Overall the shopping experience with MetalMark is top notch. They are engaged with the community, and passionate about bringing something unique to the market. I'm looking forward to seeing what these guys come up with next!
