N7CFO Key Collection
• I have been collecting since 1980
• At one time I had 1200+ items – I
am now in rehab and now have
only 600+
• The collection is available for
viewing by appointment

N7CFO Key Collection
• I built a database that indexes over
5000 key ads over a 150 year
period
• I used to publish the N7CFO
Keyletter, an occasional newsletter
about key collecting. It was
trampled by the internet!
