We had no idea that any others existed until about 4 weeks ago when Rich Hanover emailed me. The ones Murph sold were sold back in July and August of last year. IF, my memory serves me correctly.

There was an ad in the last club magazine that was put in for a deadline, about the 1st of Nov. No sets were sold from that ad, although one set was traded for equal value.
Chips are found all the time. The numbers being quoted here would not change TCR value by much IMO.
There are still only 76 complete sets known at this time.
