Later, after his war service (including a year in a POW camp in the U.S.), he went on to study philosophy, literature and history.
In that year the collection was received by the Bavarian Mortgages and Exchange Bank (Bayerische Hypotheken- und Wechselbank, now HypoVereinsbank).
Pick was retained as a curator in the service of the bank between 1964 and 1985 and continued to expand the collection.
Albert Pick lent his name to the Pick-numbers system, whereby collectors can unambiguously identify and catalogue each banknote.
Besides his best known work, the Standard Catalog of World Paper Money,[2] Pick published numerous books abroad and received several international prizes and honors for his publications.
