I did some research on these guitars and the are in pretty good demand. Your 100 series Maton guitar circa 1970s would sell for $800-1200 at auction and on the secondhand market Your 12 string Mayon guitar would sell for $600-900. If you want to sell these ask the top price at first. You can always lower the price later.
