The Winged Victory of Samothrace
A dog woman
Hercules & Telephus
A sphinx is an Ancient Egyptian statue (only one, I believe), where it has the head of a woman, body of a lion, and wings of an eagle.
'Bust ' can mean a number of things, -a woman's breasts, a statue of head and shoulders, or colloquially, a sudden failure.
A head louse does not have wings. It is a wingless insect.
Nephthys was depicted as a woman with the symbols for "basket" and "house" on her head. She at times had wings, and held the ankh.
The statue you're referring to is likely the "Colossus of Rhodes," which was a giant statue that depicted the sun god Helios. However, if you mean a more contemporary representation, it could also refer to "The Head of a Woman" or other bust sculptures. Statues that feature only the head and shoulders are commonly known as busts, which are often used to represent notable figures in art and history.
About $14 or $15, depending on how worn it is. Your coin is an example of the famous Morgan dollar series, named for the artist who designed it. The woman's head is of course (!) Miss Liberty, with an image similar to the one used for the Statue of Liberty.
a crown on her head
Yes, the entire statue is hollow.
Benvenuto Cellini's statue of Perseus holding the severed head of the Medusa.
That statue is called the Sphinx.
