I myself came in to find a coin for my father, who loves to collect, unfortunatelly I wasn't treated respectfully. I found myself waiting for someone behind the desk to assist me but he was to busy talking with friends. 10 minutes later, I asked several questions only to be told, rudely, any more questions, buy a book or find it online.
Now mind you I simply asked three questions:
1) Do you have a 1987 Silver half dollar American dollar?
2) Would I be able to place this item in lay-away.
3) And would you have a rare coin around the price range of $50.00?
I hope this helps
