It depends a lot on what you mean by "a lot".
In any case no current circulating $1 coins are worth more than face value. You have to go back to $1 coins that were made of 90% silver (1794-1935) or 90% gold (1849-1889) before you come across any that are worth a significant premium, say $1000 or more.
Of course any silver or gold coin will be worth at least as much as its metal value, which changes every day. As an example a common-date silver dollar would be worth around $20 to $22 as of 02/2011, while a gold dollar would be at least $130.
However a rare collectible could be worth thousands of times that much! Just a few samples:
$1 gold
1875 : $500 to $74,000 depending on quality
1861-D: $32,000 to $171,000
$1 silver
1921 Peace: $80 to $150,000
1893-S: $2,250 to $1,150,000
1870-S: $108,000 to $1,231,000
1839: $4,600 to $250,000
1795 small eagle: $1,400 to $569,000
And of course the "1804" dollar. These were actually struck in the 1830s but have sold for as much as $7 million!

The Balboa is the same as the US dollar. We know that US silver dollars is worth more as the Panama silver Palboa. In Panama the currency is US but there are Balboa dollar coins. Also, the silver coins in Panama are the same size as the US coins and would be worth more as the US silver coins.

It depends on what you think a lot is and which US coins that have Indian heads on them you are asking about?
