If genuine, and depending on your definition of "valuable", yes. Maybe $20-$30 if it is an actual no FG 1969 D cent. Just guessing on the value, but probably close.
I actually have a fair amount of pennies from dates like the one that you mentioned without initials...
Get the mobile app for PCGS on itunes or from their website, they have actual coins that show different grades.
The value of your coin depends on its condition. You should start your own thread and post clear images of the obverse and reverse in the What's it Worth Forum (instead of highjacking a 2 year old post).
1 cent, bud. If it is in Mint State condition it could be worth more. They made millions and millions of these.
