Answer 1

This interesting extract says the term "pocketbook", referring to a purse, is becoming less common also in the U.S. where it is used to refer to a (hard sided) handbag

• The largest difference between Canadians and Americans was the American use of the old English term ‘pocketbook’ which originated from a type of wallet that fit into the pocket in the 18th century The term was first used to describe a woman’s hard sided handbag in 1816, as opposed to a drawstring closed soft-sided reticule (aka dorothy bag).

• Pocketbook is now an archaic word in England and Canada and becoming increasingly scarce in the U.S. but is still used by some to describe the difference between a soft and hard sided handbag.

• For the English, a wallet is a masculine style of purse, whereas in North America there are men’s and ladie’s wallets, with men’s wallets (aka billfolds) being smaller to fit into back pockets of trousers (or as Americans would say – pants).

Answer 2

I am a native of upstate New York. In my idiolect, "pocketbook" immediately conjures the meaning of "purse/handbag" and never the meaning of "wallet."

Answer 3

My paternal grandfather was born in Ijamsville, Maryland in 1904 and all my life I heard him refer to his wallet as a pocketbook, at least when he was at home. In my teens I asked about it, and he said that is what the locals called a wallet when he was growing up and that once he moved to Washington, D.C. to attend college, it took him many years not remember not to call it that. I've never heard any other person refer to as such, so if that was a Frederick County Maryland colloquialism, it died out by the time I was born in 1962.
