Did you purchase these recently direct from the artist or at an auction?
These are contemporary works that are derivative of the style of the late Basquiat, however, Frank Charles Dante Minutos has not yet established a substantial auction record history on the secondary market. The insurance values would be based on his direct sales prices at gallery or through his studio directly. The re-sale value, based on comparable would be in the $200 - $400 range per picture. There were works by this artist sold through a charity benefit fund raiser auction conducted by Heritage Auctions in Texas. You can try contacting them, for no fee, through their website at www.ha.com.
