It looks very nice. How come we don't get to see your baby pic?!
It's a nice postal history item. I'm not that knowledgeable about postal history, but I would think it should fetch $25-$50, maybe more if you find the right buyer. However, to even get it to sell in that range, you would have to find the right buyer who has an interest in this type of postal history item, and that is not always that easy for an item of this nature.
The stamp sheet itself (without the signature and presentation folder) is relatively common and retails for <$10, so the main value is in the specific postal history. That's why you will need to find the appropriate buyer.
