Are they reliable? What kind of silver to buy?
Find a local coin shop and tell them you want $XXX of silver and you want the most weight per dollar. They will tell you to buy coins because there is no tax on it. Some local coin shops aren't just coin shops they have other streams of income like having an insurance company as well. If you can find one like this you will likely get a better price than online.
Call them 1st and see if they have it in stock. They move a lot of metal.
Buy what every shiny you like, I like the silver krugerands,they have a lower premium than American eagles.
I don't know i haven't bought from them, but i'd get silver US dollars.
The real kind.
And yes, Scottsdale is legit.
