I got banned from a Coin store. Can the store owner ban me from other stores and/or coin shows?

Any stores he owns, yes.

He can't ban you from other stores unless he owns them. It sounds like a person argument between the 2 of you, which will die down if you never see each other again.

He can't directly ban you from other stores, although he can certainly talk about your behavior with the owners or managers of other stores. They might not welcome you then, but that's not his decision. Unless he is running the coin show, he can't ban you from those.

The coin store owner can ban you from his premises only. You are free to visit other coin stores and attend coin shows.

He can't ban you from anything but his store. But he can talk to other people, and they can decide to ban you (or not) from their stores.

Only stores and events he controls.

No, he does not have the authority to prevent you from entering other establishments or coin shows.

In the mean while, since you have been on notice not to enter his store, do not do so or you can be arrested trespassing.

From this incident, you should learn that you must conduct yourself in an orderly and respectful fashion. I have been able to tell someone off in the kindest way and with a smile without losing my temper or resort to name calling. You should, too.

No, he can only ban you from his store, no one else...

Private property.

After reading your rant, I would ban you too.

Of course he can banish you from his store. It is his business. No, he does not have authority to stop you from attending coin shows unless he is a part owner or manager of those or he informs others to do the same.
