I wonder if A R Alexander was the priest who helped my early interest in coins at school? He was Father Andrew (Alexander) and he had an extensive collection of British coins. He was always happy to help us boys with identification and grading of coins. Also smoked Balkan Sobranie in a pipe, which was very impressive to a 12 year-old.
He was one of the good priests at the school. (Don't ask about the bad ones.) He died only a couple of years ago having spent the previous 20 years in a rest home for priest in the school grounds. I kept meaning to arrange to go to see him, but now it is too late.
