It is worth at least $5, as it can be used for postage for that amount. Depending on the version, it could be worth a great deal more. Very high value stamps such as this are not common, and some of the earlier $5 stamps can be worth as much as $3,900 for the Columbian $5. Consult a stamp catalog to identify the specific version and what its value might be.
I believe you are referring to the Bobcat pictured on Scott US #2482. It has a good value unused, it can be purchased for $7.95, a dealer might pay a couple dollars for it.
The value of these stamps is usually $6.00 per stamp. Scott specialized catalogue I have a complete booklet of stamps, 50, mounted as purchased in 1943, with my signature and other descriptions and details on the covers. Does this make the booklet and stamps more valuable? What would be the best way to sell it, if I choose to, by auction or which method?
That would be Scott Number US 1395. An unexploded booklet has a catalog value of $25.
I have not quite sure what you mean by "Lady Liberty stamp", but except for some pre Civil War stamps, all unused US stamps are still good for postage at the price they sold for ( no adjustment for inflation.) The one exception is the new "forever " stamp which sell for current the first class rate, but automatically jumps in value when rates go up.
I do not find any such stamp listed in the US catalog. There have only been four 1 1/2 cent stamps and Franklin was not on one of them. Special cancellations and different values are likely to be worth more. Consult a postage stamp catalog, usually available at your local library for exact identification and catalog values.
Barely, probably the face value of the stamp.
The D stamp has a face value of 22 cents and can be used on domestic mail at that value.
Forever
