Can you get gold dollar coins at the bank?

Excuse me, I was wondering if you could help me with a question. I've been curious about acquiring some gold dollar coins, and I was wondering if it's possible to get them directly from a bank? I've heard that some banks offer precious metals like gold and silver for purchase, but I'm not sure if that includes gold dollar coins specifically. Could you please clarify if banks typically offer these types of coins for sale, and if so, what the process might be like to acquire them? Thank you in advance for your help.
