On http://dig4coins.com/news/latest/ne...-coins-to-be-introduced-into-circulation.html I have recently read some news stating that each 3 months, starting February 14, new presidential coins will be issued; valuing 1 dollar. The first presidential coin was James Monroe’s, featuring his image on the obverse. It was the 5th president of USA. After 3 months, the 6th president will be incrusted on the next dollar coin. This procedure will be repeated 2 more times for the 7th and 8th, till November 13. It is an interesting method of putting in circulation valuable coins. In some time these coins will be an interesting material for collecting. It’s a pity they issued only 4 presidents… very few.
