I think a new one just came out this week.
If it is a fair coin then the probability is 0.5
It's a circulating coin, a dollar
None of the Presidential dollars are made of gold, no US circulating coin is gold, it's just a one dollar coin.
There were no coin sets made in 1789.
James Garfield $1 Presidential Coin
Yes, they are legal tender.
The only coin I can think of featuring Jackson is the Presidential $1 coin with him on it. He also appears on the $20 bill, but that's not a coin.
The next election will be in 2012.
It is worth over three million dollars due to the rarity of the coin. Be careful not to confuse this with a standard Jefferson Presidential dollar coin, which is only worth $1.
Please be more specific
$72 in mint condition.
