silver certificate?

When my husband passed away he left some silver certficates to out granddaughters. 3 of them are 100,000 dollar and 3 are 500 dollar. They are made of silver and are in plastic cases. I was wondering about the actual worth of the certificates. They are from the Washington Mint. They are.999 fine silver. The 100,000 dollar ones are a series of 1998 and the 500 dollar ones are from 1996.

For the most part they’re worth the silver content alone.
