Adrian offered my elderly mother 30% less for a valuable coin than I was able to get from another dealer. Shameful to try to rip old people off.
Furthermore, they clearly padded their Google rating a few months before I posted this. Eleven consecutive 5 star ratings in the span of a month?! Pretty convenient... That's more than they had in the several years before and since that month. Add that to their shady business practices.
Apart from that, I shopped there a few times in the past and found they had a decent selection of gold and silver coins and bullion. Just do your research and make sure you're not getting ripped off by these people... Online dealers these days tend to be the best deal.
