Mike & Pete,
I can't tell you the exact amount, but it was well over $10,000 US$. I caused a lot of excitement on the Forum when I put a picture of it on the Thread. I was getting e-mails and calls from most of the well known penny guys in the UK. I purchased it from a High End Collector, in Florida, who had owned it for many years. I delivered it, in person, at Notting Hill, in London, since I was vacationing, at the time, in Great Britain. There are 5 or 6 of these Narrow Date known (actually) at this time, with some collectors having multiples.
This is a good test for Zooy, as the listed estimates for really rare coins, are somewhat low, in most cases, compared to actual sale prices. I wish I still had it!
