While you can buy circulating coins at a bank, American Silver Eagle coins are typically not available for purchase at most banks. However, some banks may have deals with local coin dealers or offer precious metals investments through Precious Metals IRAs, though this is not very common.
The U.S. Mint does not sell American Eagle Bullion Coins directly to the public but through authorized dealers.
If you’re interested in purchasing American Silver Eagle coins, your best bet is to look for an authorized dealer or a reputable online platform specializing in precious metals.
