I've bought from them a few times and agree that they generally aren't the most friendly, but I haven't had as bad experiences as others. I do not think they are 100% fair with their pricing. I have gone in to buy silver and when the price is down they say that they have to charge by what the previous day close was, but I have gone in when the market was up and they then say that they charge what the current trading price is. They also charge well over current value. I bought half dollars when the value was at $7.80 coin, they were selling them for $9.00 then told me they would have to charge an extra 3% if I wanted to use my debit card as they weren't even making 3% on the sale.
I have bought from Bismarck Gold & Silver for over 20 years. I live out of state so I have my orders delivered. I always get great pricing and friendly service from Larry, Mark and Zach. They are a family owned business and I have always been treated very fairly. I have bought precious metals from different sources but have always trusted them the most.
They are so fair like I said before I have purchased and sold silver in five different states and there money is made when selling and they buy at market. I've been taken on both ends elsewhere by alot more. They also are coin collectors, coin books and alot more.
I just visited them on Sep 25, 2015 and found them to be very professional and helpful to a new collector like me. Nothing unprofessional or mean about these guys. I will absolutely go back to them...often.
