Usually they are available at a coin dealers shop. The proof and special finish uncirculated is available from the mint. There has been a drain of Silver Eagles due to the value of silver and the mint has stopped selling them (2208), older ones are available from coin dealers not the mint, due to a run on them and they are out right now. Dealers supply of new and older ones may be getting low also. If that is the case this is not the time to buy them for they will be more money for they are rare now. Wait a couple months until the mint catches up.Since they are worth far more than the dollar that is one them, you will not find them at banks or be able to get one for $1. I would try a local coin dealer for a web dealer will take your money and may say he has none and you will have to wait until he does before he ships it too you.
