Fishing with an un-baited rarely is successful. I'd think hero would be better served to slide on a huge, juicy "worm" that would tempt someone who wasn't normally inclined to sell such wonderful chips.
If you want a set out of my closet, you will need to make the deal wonderful. No promise of success, I don't much care about the money and someday not so soon I'll restart poker.
No doubt there are other people not quite as greedy as me. I know there are hundreds of thousands of these chips in the hands of greedy chip horders. You only want 400 - 500 chips, how much could it cost? I think $4,000 to $5,000 might get the job done.
And don't get your hopes up vis-à-vis me. I almost never sell my unwanted chips. Chips that I plan on using might require one to deal with the executor of my estate. -=- DrStrange
