Well I know of a few. I am not in queens. I live up state a bit in middletown. In middletown there is a very good location it is called DART coins. Dart has a huge selection of coins and he supplies most of the other local smaller shops in the area.
A good place for bullion is in nyack. I forget the name of the store but the owner is mike and he also deals with paper PMS. he is a stock broker with a store front. The store usually has a decent supply of bullion and he will order bullion if you request it.
