If you want to make an appointment online at 11 o'clock and go to the downtown area half an hour in advance, you must see clearly the bags and cameras. You'd better not take pictures without bags. You can see the coin production process for 45 minutes. There's also a lot of gold. The silver and other currencies exhibition bought the state quater collection memoir and exchanged $2 for the new Presidential Hill. The commemorative coin is not bad.
