Contains about 1/4 lb. of silver pigment. Assumptions: Jar is 8 oz.  Est. pigment is half of that.  Oil-base.  Based on $870/kg (Spot today), the amount of silver here is worth about $87.  Sell for half price.
Got this sample while at GE in the 1960s.  We used it for painting conductive paths on custom circuit boards.  Not opened since then.  Still moves in the jar.  Will need some thinner and serious stirring.
