Too late to revise the title to add the word China because of the bidding, but you can revise your listing and mention the word China and it might help you get more people looking at it.
Maybe you should include a link to this thread on your listing, it might help change the views of some of those doubters out there.
Only $1,249? Its probably not a very good marble. Yeah Right!! I think its doing great. I hope you didn't set your reserve to high. It might get up over $2,000 just yet. I hope there's a killer bidding war at the end. Swiz
Congrats on finding such an awesome, beautiful marble. I'm glad to see it's doing so well. I have to say it's really adorable. Perhaps it was thrown away when the kids grew up, but I like to think I would keep it because it is so cute and would remind me of my kids. Then again, it might have been dropped. It's fun to speculate about these things.
That is one great marble and congrats!. I wouldnt let the doubters of the authenticity get to me as most are probally jealous they didnt find it.The real hard core marble collectors know the truth and im sure that will be shown at auctions end.
