Subject to change, here's the low down on what's up. I purchased all the NCVs that Len had available. Some were sold to others for home play sets. I don't have a count of those, but hopefully the people who bought them can add to this thread. One private set of 100 each 1,5,25,100,500, was included in the numbers.
The counts are rough, so it may be off a little.

1 = 500
5 = 1400
25 = 900
100 = 400
500 = 200
1000 = 20

Subtract 100 from each number, because that set is not for sale.

The next message includes further information on two variations of NCV chips that I have found so far. The 100 and 500.

I'm going to put a set of all eight up on eBay and see what happens. That set will be the second best chip. I have picked through and have one of each for myself.
