<prompt> Human: I have 235 pounds worth of GBP notes - 10 twenties, 2 tens and three fives. Last time I was in England, about 12 years ago, I was told that theyre obsolete and Id have trouble changing or spending them. They were acquired by my parents in the 1980s - they would bring currency home with them so theyd have walking-around money for their next trip but never made it back again before passing. Where can I convert these to USD? Im about two hours from NYC and could go there if necessary. edited to fix bad math  <response>: You need to post them to the Bank of England in the UK and include instructions on how to pay you their value.
