A gem Cypraea hungerfordi would usually go for about $20.00 or $25.00.
Cypraea pulchra is quite variable in size, and large ones demand high premiums.
A small gem (under 40 mm) would be about the same price as a C.
hungerfordi; but a 50 mm gem might be $50.00 or $60.00; 60 mm $150.00 to
$200.00; 70 mm (very rare) could be $350.00 or $400.00.
