Based on the provided information and numismatic history, a 1964 silver dollar does not exist and therefore has no value. The U.S. Mint produced the Morgan dollar series from 1878 to 1904, and then again for a final year in 1921.
The provided context supports this conclusion, as the Morgan Silver Dollar Value Chart from SD Bullion covers the years 1878 to 1904, with no mention of a 1964 issue.
It is possible you may be thinking of the 1964 Peace silver dollar. The U.S. Mint did strike over 300,000 Peace dollars dated 1964 at the Denver mint. However, these coins were never authorized for release and were ordered to be melted down. While rumors persist that some examples survived, none have ever been publicly authenticated, and they are considered illegal to own. The eBay listing provided is for one of these unauthorized or replica 1964 Peace dollars, not a Morgan dollar.
