I believe it was started by Stanley Apfelbaum, not Applebaum.

FCI was First Coinvestors, except when the ANA allowed them again to advertise in The Numismatist after a ban - their first ad read "First Convestors".

And it was Rockville Centre not "Center". I grew up in that town.

Pete Smith's book picks up the story "Founder and President of First Coinvestors. In 1969 it was the first coin company to offer stock on the New York Stock Exchange. Associated with Pine Tree. He was expelled from the ANA in 1972 and reinstated in 1974. He proposed establishment of an independent grading board in 1973. He was appointed to the American Numismatic Association Grading Board in April 1975. In 1978 he founded the Institute of Numismatic and Philatelic Studies at Adelphi University. He served as the Executive Director of the institute. He formed a new company, American Coin and Stamp Ventures Inc"

I lectured at Adelphi; there are tapes of many of them (packaged and sold). I s4till have a set in my library
