The chips being sold on ebay were supplied by me to the seller.
David Sarles and I bought a quantity a few years ago and donated most to NHS. We only kept for sale half a dozen sets plus a few extra $1 & $5.
The seller (Dan Abernathy) was one of the first to buy a set.
I have one complete set left here which I actually 'bought back' when I got Michael Richter's collection.
