The provided context is not relevant to your question. Based on general knowledge, the answer requires a key distinction between different types of dollar coins.
Generally, you cannot buy silver dollars from a bank. Banks deal in currency at its face value, and true silver dollars, such as the or Peace dollars minted in 1964 and earlier, are worth far more than their one-dollar face value due to their high silver content and numismatic value. These coins are considered collectibles or investments, not circulating currency.
You can, however, obtain modern dollar coins from a bank. These may include the Susan B. Anthony, Sacagawea, or Presidential series dollars. While you can ask a bank for rolls of these coins at their face value of one dollar each, they are made of metals like copper, zinc, and nickel, and they do not contain any silver.
On very rare occasions, an old silver dollar might be deposited at a bank by mistake and could potentially be acquired by a customer. However, this is extremely uncommon and not a reliable method. To purchase genuine silver dollars, you should visit a reputable coin dealer, a precious metals broker, or a numismatic show.
