Yes, there were several US silver coins made dated 2000, none though were intended for circulation. There were silver eagles made ($1 coins sold as silver bullion and are 1 troy ounce of silver), along with silver proof sets (with 90% silver dime, quarters and half-dollar) and a few silver commemorative coins made. Not to mention many foreign silver coins.

Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
Check the date again. These coins were not made in 2000.
