USA Coin Book was created by an 18-year expert of coin collecting - unemployed physicist with computer programming and web development experience. We know what our coin collectors want and one of our philosophies is to make this site as simple, organized and easy to use as possible. That means organizing coin prices and values in such a way that a visitor can reach any coin price with literally only one click from the homepage. The idea itself to create this site started out of the blue on June 12th, 2010 along with the purchase of the domain. Development then began and this site launched shortly later on August 6th, 2010.
We also tried to make this site provide a sort of marketplace atmosphere for buyers and sellers. Members can view collections from other members and access their entire "Coin Book" consisting of their sales inventory, auctions, wishlist and personal collection by viewing their personal page. We know this kind of feature can come in handy if you are a coin dealer or if you want to get on the computer and quickly show people your inventory over the internet on a single page. Source
