If it doesn't have a nameplate, it's most likely an Asian made import. You'd be lucky to get $400-$500 for it from someone in the business who is looking to resell it, but you might $800-$1,000 for it if you sell it directly to someone, with accessories. Keep in mind the buyer will have to pay the installer / mover +/- $400 for the labor to get the table disassembled, moved, reassembled, and leveled, even if reusing the same cloth and even if it's a local buyer.
