what is a quid vs pound

A "quid" is a slang term for the British pound sterling, or the British pound (GBP), the official currency of the United Kingdom. It equals £1 and is not pluralized. The term "quid" is believed to have originated in the late 17th century, and its precise etymology is still unknown. It is commonly accepted that the Latin phrase "quid pro quo," which means "something for something," is the source of the term. So, essentially, a quid is just another name for the British pound, with no difference in value. One pound sterling is equivalent to one quid
