They are in Beaumont, TX. There seems to be a lot of coin shops in and around Beaumont for some reason. Anyway, their BBB profile shows that they have been in business for over a decade and they have no outstanding complaints, FWIW:
My order arrived today, 5 1921 Morgan Silver Dollars (BU) in plastic cases.
I did a search of my financial software program and found a previous transaction (two actually) with this company.
On 1/27/2016 I charged $523.90 with them. But on 2/12/2016 I received a $503.00 refund. I cannot remember any of the details, but it must have been something I was dissatisfied with and returned. The difference between the two was probably shipping. I just cannot remember the details.
Morgan Silver Dollars are about the only coins I buy other than ASEs, Canadian Maple Leafs, and Buffalo Silver Rounds.
