Origin

The earliest recorded use of the specific "trash to treasure" expression is found in Hector Urquhart’s introduction to "Popular Tales of the West Highlands" in 1860. However, similar expressions existed earlier, evident in writings such as "One man's meat is another man's poison" from the 17th century and various early 18th-century texts that highlighted themes of subjective worth and contrasting values.
