Actually it's Liberty walking not standing. It's one (Troy) ounce of silver with a current values of $34.86.
It is worth it's silver content so it would be worth about $2.50 to $3. (As of 10/7/11)
A 1992 American Eagle Bullion Silver Dollar in MS65 condition is worth: $24.00.
Standing Liberty Quarters have vastly different values depending on their grades. If your coin is well worn, that is, if you can't see the full union shield on Liberty's shield, it is worth about $6 for the silver in it. If it is in better condition, it can be worth around $30-50+ depending on its condition. It isn't a rare date but high-grade standing liberty quarters are always in demand and if it is certified as a high grade (MS-63+) it can be worth over $100.
There is no true Standing Liberty half dollar. They are properly called Walking Liberty half dollars. But if you are asked to buy a Standing Liberty half dollar you can be safe to assume that it is a Walking Liberty. Review the Standing Liberty quarter and see that the figure is in an obvious 'standing' stance whereas the Walking Liberty appears to have motion.
no the liberty tree is not standing loyalist cut it down it was replaced by the liberty poll.
