Here's link to an auction for a group of Black Orchid $1 and $5 chips:
https://www.ebay.com/itm/313621999993?hash=item490553f179:g:3sYAAOSwobhhBHkE

Specifically, 51 of the $1's and 21 of the $5's.
Final price not shown, as it was a "Best Offer Accepted" deal.

These Black Orchid chips have been dribbling out for the last 10 years or more. Usually 1 at a time with some breaks.

I don't recognize the seller. Anyone here buy or sell them? Not my auction / no involvement in it. Just reporting the info.

Unknown if there's still more out there or not.
