I have purchased from TSC twice, and both times the items were returned. I even showed the items to a dealer friend, and his first comment was, “where did you get this, the shopping channel”. If you are going to buy RCM items from TSC, then I am sure you will do fine, but it seems that most RCM items drop in value price after they are sold by the mint.
Now that being said, I have been to Steven’s shop, and have bought some really nice notes, but like always buyer beware, you must know what you are purchasing, how to grade the notes, and what the market prices are.
If you want really nice and/or rare notes or coins outside of the RCM items, then the shopping channel is probably not for you.
