How Old Is My Grandfather Clock And What Is It Worth?

I also have  "The Rittenhouse Grandfather Clock " with the certificate of authenticity made by the Pearl Clock Company.  My grandmother purchased it in 1985 as a limited edition of 6000 through the Franklin Mint. The purchase price was $900 but I don't know the value of the clock now.

Nobody can tell you the exact date. The Rittenhouse Clocks were made in the 18th and 19th century- It was first created by David Rittenhouse. (about david's life >>> www.oldandsold.com
