The American Eagle Proof Program was first introduced in 1986 with the sale of gold and silver proof coins. Proof silver coins are the finest quality coins of any issue. Proof coins are masterpieces of craftsmanship. Clean, good quality steel is used to make proof dies. The die impression is grit-blasted with very fine zirconium sand to give the surface a frosted finish – the common term for this is sand-blasting. The surrounding background is then highly polished. Hand polishing of the sections of the die face is performed under a microscope and takes two to three hours. To achieve a mirror-like finish, different grades of diamond lapping paste are applied to the surface and polished with wooden sticks birch wood. Polishing with a soft felt pad attached to a dental drill follows this.
Proof silver coins are great for investment over the long term. The initial cost usually outweighs the value of a short-term investment.
Proof Silver Eagle coins are the collector versions of the official United States bullion coins and are also available in other denominations. Proof Silver American Eagle coins are minted at the United States Mint at West Point bearing the “W” mintmark.
As a result of the global recession, the demand from investors for Proof Silver coins as a hedge against inflation and economic downturn has risen sharply. Its intrinsic weight of the metal and supply and demand are used to judge the value of a Proof Silver coin. These factors are what allow Proof Silver coins to offer the best growth potential over the long term for anyone seeking to protect their overall assets.
