Can one still sell antique ivory chess set?

Only if you can find a willing buyer.

Se How to sell ivory artifacts

Definitely would have to be a street sale, perhaps a swap meet? Or Craigslist Ad? I’m pretty sure an oddities store would purchase it.

I’m nearly positive you can see antique (pre-ban) ivory products.

@augustlan I think you can see pretty much anything.

Crap. Obviously, I meant “sell”. Thanks for pointing that out, @XOIIO.

It’s a pre owned item, antique even so you’ll have no issues with legality to re sell it.
