Thank you :)

No, haven't thought about it. In my experience, pieces don't go just by putting them on online marketplace but I might be wrong or doing it wrong.

I usually sell because it's exhibited physically.

Auctions I have to admit I'm totally unfamiliar with, I mean, of course I get the principle but I never did any. Also I don't see much (yet) "take my money" enthusiasm, I'm really unsure how would that work without it. But again, I have no idea.

Wouldn't even it be detrimental if the auction fails?

Thanks for the ideas anyway ;)
