Can you safely put metal posts (like those on 1965 Bank-A-Ball) in an ultrasonic cleaner? Or is cleaning them by hand with metal polish or another substance preferred?

A session in a tumbler does the job very well.

Since I don't own a tumbler, wondering if my ultrasonic is safe for them or not.

I have done many nickel-plated items in my ultrasonic with no problems. Make sure whatever you use as a cleaning solution is compatible.

chuck them in a drill and use a well worn red scotch brite pad.

I like Never Dull myself. A can is like 5 at almost any auto/dept store.

I did these by hand with mothers chrome polish.

The fast way I did mine was chuck them in cordless drill and used Mothers mag wheel polish and a soft rag. I have a tumbler but it takes longer.

Keep in mind--clean first to remove any dirt or residue, then polish to shine them up. Those are typically two separate steps.

Yes, I typically clean and then polish, was just wondering specifically about the ultrasonic. Did that last night and they turned out great. Tonight they'll get a good rub-down with Mother's.

Speaking of polishing, if I wanted to get a buffing attachment for my drill (for larger metal parts like coin doors, etc.) would something like this work amazon.com link » or would you guys recommend a Scotch-brite buffing wheel or something like that?

I don't plan to invest in another power tool -- just want to know specifically what works best on a cordless drill.

i would not bother then, do it all by hand or get a grinder/buffer big motor setup. i think the cordless drill things would be a waste of time and money. imo

Quoted from ForceFlow:

Yup. In many cases, they have substantial pitting or tarnish which needs to be addressed before they are polished. Sometimes they only need a polishing, but that's if they are decent to begin with. I've had some that were practically green. They needed a few days in the tumbler, then polishing on a lathe with Mother's metal polish. Even then some of them don't shine up really good. Just too far gone.
