Since silver certificates have not been produced since the 1960's, I assume that you're asking about a privately issued ingot that is cast in the shape of a dollar bill. I would guess that it is worth its bullion value (silver as of October 9, 2007 is $13.45 per troy ounce).
Please check again and post a new question. No US $100 bills are dated 2000, and the last $100 silver certificates were printed in 1891.
1 dollar
well-worn = $350 lightly worn = $1000 crisp uncirculated = $2000 ... as of 12/22/09
The last US $2 silver certificates were dated 1899, and no $2 bills were printed with the date 2000. What you have is probably a privately issued replica intended to celebrate the year 2000. Unfortunately once the celebrations were over, there was almost no market for any memorabilia so it has very little collector value.
About $17.00.
Check the date again. These coins were not made in 2000.
It's a 2000 one-ounce Silver Eagle bullion coin and as of today is about $18.00
It's worth its weight in silver.
Sorry the US mint does not strike $5.00 silver coins
If you are referring to the 2000 Millennial Set, it has a value from $24 to about $15,000 depending upon the condition of the coins.
Colorized bullion coins have no numismatic collectible value. Unless you find someone that wants it, the value is only for the silver, about $23.00 as of today.
A 1948 uncirculated silver dollar that has benn certified uncirculated depending on grade would be worth 2000 dollars and up
